Conservation agriculture has three basic principles:
- Disturb the soil as little as possible. The ideal is to plant direct into the soil, without hoeing or ploughing. …
- Keep the soil covered as much as possible . Mulch, special cover crops and/or crop residues left on the field protect the soil from erosion and limit weed growth …
- Mix and rotate crops. Planting of the same crop each season – as sometimes practiced in conventional farming is minimized by planting the right mix of crops in …
- Challenges for conservation agriculture
- Minimum mechanical soil disturbance. (i.e. no tillage) through direct seed and/or fertilizer placement.
- Permanent soil organic cover. (at least 30 percent) with crop residues and/or cover crops.
- Species diversification.
What are the principles of Agriculture?
This run-through looks at the principles of providing the soil with armour, employing cover and catch crops to maintain plant cover/residues at all times to protect the soil from adverse conditions. Ensuring living roots are always present in the soil underpins soil health and regenerative agriculture.

What is conservation agriculture?
Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands. It promotes maintenance of a permanent soil cover, minimum soil disturbance, and diversification of plant species.
What is conservation agriculture PDF?
Conservation agriculture (CA) is characterized by minimal soil disturbance, diversified crop rotations, and surface crop residue retention to reduce soil and environmental degradation while sustaining crop production.
Why is conservation agriculture important?
Land – Conservation agriculture improves soil structure and protects the soil against erosion and nutrient losses by maintaining a permanent soil cover and minimizing soil disturbance.
What is crop rotation?
Crop rotation means that different crops are alternated in the same field, preferably cereals (maize and wheat) followed by legumes (beans).
How does fertilizer help soil?
Protects the soil against erosion by water and wind. Improves infiltration and conserves soil moisture. Increases yield per unit of fertilizer or manure applied. In the long term decreases the amount of fertilizer per hectare. Cost savings: fuel, time and labour costs in the long term. Improves soil organic matter.
What are the three principles of sustainable farming?
This sustainable farming method is based on three principles: crop diversification, minimal soil movement and permanent soil cover. If not practiced sustainably, agriculture can have a toll on the environment, produce greenhouse gases and contribute to climate change. However, sustainable farming methods can do the opposite — increase resilience …
How does conservation agriculture help the environment?
Conservation agriculture conserves natural resources, biodiversity and labor. It increases available soil water, reduces heat and drought stress, and builds up soil health in the longer term.
What do farmers use to remove weeds?
Organic farmers apply tillage to remove weeds without using inorganic fertilizers. Conservation agriculture farmers, on the other hand, use a permanent soil cover and plant seeds through this layer. They may initially use inorganic fertilizers to manage weeds, especially in soils with low fertility.
What is the difference between organic farming and conservation farming?
However, the main difference between these two types of farming is that organic farmers use a plow or soil tillage, while farmers who practice conservation agriculture use natural principles and do not till the soil. Organic farmers apply tillage to remove weeds without using inorganic fertilizers.
What is sustainable intensification?
Sustainable intensification is a process to increase agriculture yields without adverse impacts on the environment, taking the whole ecosystem into consideration. It aims for the same goals as conservation agriculture. Conservation agriculture practices lead to or enable sustainable intensification.
What is zero tillage?
Zero tillage is combined with intercropping and crop rotation, which means either growing two or more crops at the same time on the same piece of land, or growing two different crops on the same land in a sequential manner . These are also core principles of sustainable intensification.
How can sustainable farming improve resilience?
However, sustainable farming methods can do the opposite — increase resilience to climate change, protect biodiversity and sustainably use natural resources . One of these methods is conservation agriculture. Conservation agriculture conserves natural resources, biodiversity and labor.
What was the practice of conservation agriculture in Africa?
Across wide areas of Africa, conservation agriculture principles used to be normal practice, before ploughs were introduced. Farmers would cultivate by hand, often with hoes, rotating crops and fallowing fields for several years. Rising populations and ploughs changed all that.
What is conservation agriculture?
It is a way to achieve sustainable agriculture and improve livelihoods. Conservation agriculture has three basic principles: 1 . Disturb the soil as little as possible .
How does conservation agriculture improve food security?
Conservation agriculture (CA) has the potential to enhance food security through increased and stabilised productivity and sustainable land management (SLM). Building on indigenous, scientific knowledge and innovative equipment designs from Brazil CA is spreading in Africa. More than 14 countries are now practicing the technology. Practicing farmers are able to produce more food more reliably using same rates of fertilizers and using much less labour (up to 50%). Action is needed now to get this promising technology adopted by as many farmers as is possible. But, there are serious challenges to be overcome to make this viable. Experiences of the African Conservation Tillage (ACT) in Enhancing Access to CA Knowledge & Information and Partnerships are summaries in the rest of the discussions.The ACT is a ‘Not for profit’, voluntary membership Non Governmental Organisation registered and with offices in Nairobi Kenya. The organisation has received support from many international organisations including GTZ, FAO, CIRAD and SIDA. The common vision was developed in Harare in 1998. The current membership stands at 1200 Individuals and Institutions from 33 countries. The organisation has regional offices in Nairobi, Harare and Ouagadougou office.
What is organic farming?
Organic farming involves growing crops and livestock without using agrochemicals. It is possible to do conservation agriculture in an organic way (without using fertilizers, herbicide s or pesticides), but many types of conservation agriculture use these agrochemicals – but in small amounts and with care.
How many hectares of land were under conservation agriculture in Zimbabwe in the 1990s?
A moderate use of herbicide s was needed to kill weeds. By the mid 1990s, nearly 4000 hectares were under conservation agriculture – all on large-scale farms. Efforts are presently being made to transfer this success to some of the many new small-scale farmers in Zimbabwe.
What is agroforestry?
Agroforestry is a combination of trees and crops (or livestock), and is a form of ‘sustainable land management’. Agroforestry promotes soil cover and crop rotation, so may contribute to a conservation agriculture system. For more information on agroforestry. 2.
What is sustainable land management?
Sustainable land management (or “land husbandry”) is a broad term that includes various types of crop and livestock production that aim to produce good yields year after year, while conserving soil and water resources. It does not necessarily include all three principles of conservation agriculture (don’t turn the soil, keep the soil covered, and rotate crops). Conservation agriculture is a type of sustainable land management.
