What might a newer conceptualization of soil management for sustainable agriculture look like?
What might a newer conceptualization of soil management for sustainable agriculture look like? Under new ideas of organic matter cycling, an updated framework would likely still need to promote different types of organic inputs because early-stage decomposition is still governed by plant nutrient chemistry ( Cleveland et al., 2013; Cornwell et al., 2008; Hector et al., 2003; Papa et al., 2014 ). This means that labile recent litter inputs will decompose faster and provide more nutrients to plants, as conceptualized by Palm et al. (2001). However, instead of promoting recalcitrant inputs to build long-term stable SOM, a new framework would emphasize organic inputs as a function of their likelihood to stabilize. Because stable compounds are known to be low molecular weight in origin, one might propose increasing inputs of low molecular weight compounds to soil as a means to build up SOM. These compounds are often produced by plant roots in the form of carbohydrates, sugars, organic acids, and other compounds. This could lead to the following principle of organic matter management for ecologically intensive agriculture: Maximize the input of nutrient-rich aboveground inputs for short-term nutrient needs; for longer-term organic matter, maximize root exudation—particularly through fine roots that actively exude and cover a large area of soil—both spatially and temporally.
What is an agroecosystem?
Agroecosystem. An ecosystem under agricultural management practices. Biocontrol. Control of agricultural pests by the use of predators and other beneficial organisms (e.g., control of turf grass crickets by parasitic nematodes).
What is tillage in agriculture?
Tillage is a fundamental aspect of agricultural management that changes soil either physically, chemically, mechanically, or biologically to create suitable conditions for seedling germination and plant growth. Tillage practices are generally classified as conventional (full tillage), conservation (reduced tillage), and no-till. Conventional tillage represents the greatest level of disturbance and includes one or more passes with the following possible tillage implements: moldboard plow, disk plow, disk chisel, twisted point chisel plow, heavy-duty offset disk, subsoil chisel plow, and bedder or disk ripper. Systems with other tillage practices, such as a single pass with a ridge till implement, mulch till, or chisel plow, lead to intermediate disturbance of the soil and are classified as conservation tillage (Culman et al., 2014). No-till management is characterized by the use of seed drills and fertilizer or pesticide applicators with no additional disturbance events or implements. The influence of tillage practices on N2O emissions includes (1) fossil fuel burning during field operations; (2) their influence on soil carbon emissions and vertical distribution of carbon and total soil carbon stocks (Paustian et al., 1997 ); and (3) direct impacts on soil N 2 O emissions. This section focuses on the effect of tillage practices on N 2 O emissions from soil.
How does agriculture affect soil?
Agricultural management practices (e.g., tillage and reconsolidation; no-tillage and surface residues; plants and crop rotations; irrigation, manure, and fertilization practices; and grazing management) are major sources of temporal variability of soil properties and processes. Changes in soil properties and processes, in turn, impact soil water, mass transport, plant growth dynamics, and the environment. Weather-related factors such as freezing–thawing and wetting–drying may modify the management effects. Numerous field and agricultural modeling studies have shown evidence of the significant management effects on soil–water–nutrient–plant properties and processes. Important areas where agricultural models have been used to help investigate management effects on soil properties and processes include: (1) predicting effects of tillage and natural reconsolidation; (2) predicting surface roughness and detention storage effects; (3) quantifying the effects of wheel-track compaction; and (4) quantifying long-term no-tillage and crop residue effects, including the impacts of macropores and residue cover on infiltration.
Why is soil biological activity important?
Hence, high soil biological activity is required to facilitate effective nutrient cycling, with managements emphasizing the return of plant residues varying from high- to low-quality for decomposition, and hence high- to low-nutrient release rates. Such motivations have helped form the idea of soil health, because only living organisms can be described from a health perspective. Tied up with this concept is the idea—borne from traditional soil food web models—that belowground communities which are fungal-based will be most diverse and cycle nutrients most tightly. Research looking at the structure and successional dynamics of soil food webs under different managements (de Vries et al., 2012 )—and prior agriculture abandoned to return to grassland and forest ( Morriën et al., 2017 )—appears to support this viewpoint. There is also evidence that nitrogen addition–a wide-spread agricultural strategy–can significantly modify below-ground food webs ( Box 4.1 ). Emerging concepts in soil food webs would then emphasize the value of maintaining a large and living root biomass in the soil, to provide the labile compounds that most efficiently fuel microbial productivity and hence the soil animals that rely on this basal resource. However, the traditional view of soil food webs (which instead would emphasize the return of low quality, structurally complex, aboveground plant residues to build SOM) is still communicated as part of the scientific rationale for promoting soil biology by agencies such as the US Department of Agriculture. Nevertheless, these same agencies now stress in their practice recommendations, the importance of the living root instead of aboveground inputs for maintaining active and diverse soil communities, and similarly to promote this soil biology the need to minimize soil disturbance, to maintain plant diversity and to maintain a residue layer to moderate soil microclimate. Therefore, even if their scientific concepts are out-of-date, their advice for practice seems commensurate with emerging concepts for SOM stabilization and food webs.
How does nitrogen affect agriculture?
In agricultural systems, nitrogen addition can dramatically disrupt biotic communities that regulate ecosystem processes. Most research on the impacts of nitrogen addition in agricultural settings has focused exclusively on microorganisms, because of their key direct role in nutrient cycling processes ( Wood et al., 2015a,b ). As highlighted in this chapter, other biotic interactions are essential to regulating microbial activity and their control of ecosystem processes. Crowther et al. (2015) studied how manipulation of soil food web structure in the context of nitrogen addition—as well as warming—could structure microbial functional activity and process rates. The authors’ aim was to test whether top-down control of cord-forming fungi by isopod grazers can mediate the direct effects of external drivers, such as nitrogen addition. They hypothesized that nitrogen addition would stimulate fungal biomass and functional activity, but that the presence of fungal grazing would counteract these increases. They found that fungal biomass was greatest under nitrogen deposition where isopod grazers were excluded. Similarly, decomposition rates and enzyme potential were elevated where fungal cords were present without isopods ( Fig. 4.4 ). Nitrogen deposition—with and without warming—stimulated enzymatic activity as well ( Fig. 4.4 ). Because microbial byproducts and microbial biomass are now known to be precursors to stable SOM ( Lehmann and Kleber, 2015 ), these microbial-animal interaction responses to exogenous nitrogen addition are likely to play an important regulatory role in the buildup of SOM in the context of sustainable agriculture.
How has erosion been reduced in grazing lands?
In grazing lands, erosion has been reduced by excluding stock from gullies and riverbanks. Additionally, many gullies and eroding stream banks have been rehabilitated with engineering works and revegetation, including the reinstatement of swampy meadows through a practice known as ‘natural sequence farming’ (Williams, 2010) trapping much eroded suspended sediment. Gullies also naturally stabilise over time, and it is now over 100 years since many gullies were initiated. Thus, there are several reasons to believe that the peak of catchment loss of sediment and nutrients has passed and loads are reducing, although there is little direct quantitative evidence to test this hypothesis because of the lack of long-term river monitoring ( Rutherfurd et al., 2019 ).

What is an agricultural system?
An agricultural systemis an assemblage of components which are united by some form of interaction and interdependence and which operate within a prescribed boundary to achieve a specified agricultural objective on behalf of the beneficiaries of the system.
What is a farm system?
The terms farm system andfarming systemare often used interchangeably. Here the practice is to use farm system to refer to the structure of an individual farm, and farming system to refer to broadly similar farm types in specific geographical areas or recommendation domains, e.g., the wet paddy farming system of West Java or the grain-livestock fanning systems of Sind.
What is the resource pool in a farm system?
Element 4, resource pool:This element consists of resources which are initially present at the time of planning or commencing operation of the system – some pool or stock of land, water, seed, cash etc. which the other elements of the farm system may draw upon. Once the system begins operating, certain components of it (the resource-generating activities and by-products of the enterprises) will replenish the pool. In the schematic sketch of Figure 1.3, the arrows from the farm resource pool indicate that items from the resource pool flow to processes as well as to activities and to enterprises (as well as possibly to maintenance of the whole-farm service matrix). Strictly speaking, resources should be shown as flowing directly only to processes, since this is the level (subsystems of Order Levels 1 and 2) at which they are actually used. But from a practical viewpoint and because most of the potential processes are actually ignored in planning the operation of a farm system, resources may also be viewed as flowing directly to activities and enterprises as indicated.
What is the time dimension of agriculture?
10. Time dimension:Unlike mechanical systems which stamp out buttons or TV sets, agricultural systems rest on biological processes which occur over considerable periods of time – from, e.g., a few days in the case of quick-response agricides to 70 or more years in the case of growth and decline of a coconut palm. Agricultural systems are thus inherently stochastic: being dependent on the passage of time, ex ante,their outcomes are uncertain. Moreover, because agriculture is also a set of economic activities, the old adage applies: time is money. Other things being equal, a system which yields its product or ties up resources over a short time is better than one which yields its output or occupies resources over a long time. Strictly speaking, time is not a system component; rather it is a dimension in which the system operates. The time dimension in relation to resource use is discussed in Section 3.3.4 and in relation to farm planning in Section 9.1. The evaluation of activities which occur over long time periods is examined in Chapters 10 and 11. The latter chapter also considers uncertainty as it occurs in farm planning and decision making. Also important from a time perspective are the sustainability and environmental compatibility of the farm system being used. If, over time, the farm system is not biologically and economically sustainable or causes resource degradation, as discussed in Sections 6.2.7 and 8, this is to the disadvantage of both the farm household and society at large.
What are agrotechnical processes?
Processes may be of a biological or mechanical kind. They are a shorthand designation of all the potentially complex and interrelated physical and biological factors underlying production from crop or livestock species, only some of which may be economically relevant. They are discussed in Chapter 5.
What is the role of the household in a farm?
2. Household:As previously noted, the household plays two roles: first, it provides purpose and management to its associated farm system and, second, it is the major beneficiary of its associated farm system . Its role as beneficiary is discussed in Chapter 3. In its first role it provides purpose, operating objectives and management to the farm component of the farm-household system according to its broad domestic and social goals. Obviously these goals vary widely with culture, tradition and the degree of commercialisation and external influences to which the household is exposed. However, one would probably be not too far wrong in offering a generalization that the primary economic goal on most small farms (Types 1, 2, 3 of Chapter 2) is security and the primary non-economic goal is social acceptance (Clayton 1983, Ch. 4). If this is correct, the primary objectives for the farm are, first, production of a low-risk sustainable subsistence for primary system beneficiaries; second, generation of a cash income to meet needs not directly met in the form of food and other farm-produced materials; and third, pursuit of both of these in ways which are not in conflict with local culture and tradition. Goals, objectives and planning criteria are discussed in Chapter 6.
What is agriculture in Figure 1?
In Figure 1.1, agriculture is shown as comprising one of a very large number of actual or potential artificial systems at the sub-division level. Others are those relating to mining, transport, public health, education etc. What such systems at this sub-divisional level have in common is that each is artificial: each is based upon or draws elements from higher-level natural and social systems; and each also contains elements which are purposefully created by some human agency in order to meet its needs.

Is crop choice dependent on soil?
Crop choice is dependent upon many factors of which suitability of soil is but one. For most farmers profitability is the overruling factor, but in the case of reclaimed peatswamps there are a number of factors which influence or limit the freedom of choice and which are beyond the control of the farmer.
