Why is it difficult to digest agricultural waste?

These wastes have high fiber content that makes them difficult to digest. The size of the waste in its natural form might be too big or tough for the animals to eat. To overcome these two problems several methods were used to transform the agricultural waste into a more edible form with a higher nutritional value and greater digestibility.

How does salinization affect agriculture?

It results from natural and human activities, the latter including land clearing and excessive irrigation. Salinity due to such activities is called secondary salinity. The rising ground water during these activities dissolves salts that get deposited at or near the surface. Table 24.4 presents the global estimate of secondary salinization in the world’s irrigated lands. Vast literature on this phenomenon and its effects is readily available, a notable one being the exhaustive review by Omami [15]. Saline soils not only bring down productivity but also render the soil useless for other purposes as well (e.g., construction). It is a documented fact that high salt concentration in the soil would restrict the uptake of water and nutrients by plants. Other notable effects include damage to farm machinery, water and gas pipelines, railways, and buildings. The social dimension of soil salinity is reflected by decreasing family income and higher health expenses. Physical, biological, and engineering solutions have been developed for managing dry land and irrigation salinity conditions, and these are detailed in the study by Ongley [3].

What are the sources of agricultural waste?

Agricultural solid wastes are generated from many sources. One of such sources are pesticides, including herbicides and insecticides. It has been estimated that the global food production would fall by an estimate of about 42% if the use of pesticide is completely stopped [ 12 ].


What is agricultural solid waste?

Agricultural solid wastes are produced mainly from farming activities. However, it is not limited to the production but other activities associated with farming and food chain. Every stage and phase of the agricultural-food chain can generate significant agricultural solid wastes. The broad classification of agricultural solid wastes includes the following:


How can agricultural spoilage be prevented?

Inadequate drying technique and storage facilities—spoilage of much agricultural produce could be prevented with adequate drying techniques. If farmers have access to adequate drying technique or moisture monitor, it would have gone a long way in militating against food spoilage and agricultural solid waste, thereby enhancing food security and reducing the impact of agricultural solid waste on human health and the environment. Many of the farmers depend largely on the unpredictable solar system to dry their produce before they are stored, as well as rely on the conventional method of moisture monitoring which is neither effective nor accurate. Inadequate monitoring of moisture content in grain before storage has been reported to result in aflatoxin infestation. Aflatoxin is produced by Aspergillus flavus. Aflatoxin infestation is both a cause and a product of food spoilage [ 23] and its contamination of food and livestock feed can lead to significant annual crop losses globally [ 24 ].


What is horticultural production solid waste?

What are the benefits of recycling agricultural waste?

The benefits of recycling of agricultural solid wastes include reduction of greenhouse gas emissions and use as fossil fuel as well as contributing significantly to the development of new green markets, creation of jobs, production of bio-energy and bio-conversion of agricultural solid wastes to animal feed [ 10, 11 ].


Why are agricultural wastes mismanaged?

Agricultural solid wastes are mismanaged largely owing to ignorance. Many of the farmers and household managers who generate these wastes do not know how to effectively manage them. Many of them do not know the health implications of what they toy with, while some who know are ‘handicapped’.


How has agriculture contributed to human growth?

Increasing growth in human population has necessitated increased agricultural production. Agricultural production in the last five decades has been said to increase more than three times. Other factors responsible for increased agricultural production include technological advancement toward green revolution and expansion of soil for agricultural production [ 1, 2 ]. It has been estimated that agricultural sector provides about 24 million tons of food globally [ 1] with accompanying health risks and threat on ecosystems [ 3 ]. We cannot do without agriculture because food is a necessity across the globe, but the impact of agriculture on the environment is also evident. For example, it has been documented that about 21% of greenhouse gas emission comes from agriculture. The negative influence of agriculture on the environment, aquatic lives and human health have necessitated improvement in agricultural production, involving effective and efficient ways of handling agricultural solid wastes [ 4 ].

In the first step, pyrolysis of the biomass takes place; in the second step either direct or indirect oxygen-deprived combustion takes place during the gasification process. This process converts raw biomass into a combustible gas, retaining 60-70% of the feedstock’s original energy content.


How Does Agricultural Waste Impact Us Locally?

Los Angeles, CA is an example of how emissions affect local areas. Though most of the pollution created in this region is from high traffic and overpopulation it is a classic example of pollution effects. The city has its own weather patterns that are different from surrounding areas. This is theorized to result from pollution. Agricultural trash can produce similar results.
