How are advanced technology and fertilizer use related?
Combining fertilizer use with advanced science and technology, improved management in crop production, and a favorable policy environment to support farmers, Facing pressure to both increase yields and improve the environment, a new strategy is required to bring attention on improving fertilizer use efficiency.
Why are synthetic fertilizers not allowed in organic agriculture?
The use of synthetic fertilizers is not allowed in organic agriculture because they disrupt natural cycles, pollute the environment through runoff into our water systems and accelerate climate change.
How does fertilizer help to increase crop yields?
Fertilizer use has not only provided additional nutrients and energy to the cropping systems, but has supported a continuous increase in annual crop production. Research has shown that fertilizer input contributes about 40–50% of total yield increase for most crops.
How did fertilizers influence the development of Agriculture?
Among all factors, in fact, the contribution of fertilizers to increased yield is perhaps the greatest. The development of fertilizer use had an influence on the practice of advanced technology in agricultural production systems.
Why are agricultural extension programmes important to farmers?
Agricultural extension programmes have been one of the main conduits of addressing rural poverty and food insecurity. This is because, it has the means to transfer technology, support rural adult learning, assist farmers in problem-solving and getting farmers actively involved in the agricultural knowledge and information system [ 10 ].
Is there an extension manual for agricultural workers?
This manual is a practical guide for extension workers in agriculture. It contains simple, easy to follow tools on the commonly used extension methods and an outline of how extension may be planned and implemented. Most of sources of each subjected listed in the further reading section at the end of the manual.
The use of synthetic fertilizers is not allowed in organic agriculture because they disrupt natural cycles, pollute the environment through runoff into our water systems and accelerate climate change.
What should be included in an agricultural extension evaluation?
Day Three:Introduce the concept of sampling, review commonly used data analysis procedures and interpretation of results, and present strategies for sharing evaluation findings with diverse stakeholders (Chapters 7-10). Day Four: Participants develop an evaluation plan for a participant-identified extension program needing evaluation.
