Answers
Answer:
a)
Compost is an organic fertilizer that can be made on the farm at very low cost. The most important input is the farmer's labour. Compost is decomposed organic matter, such as crop residues and/or animal manure. Most of these ingredients can be easily found around the farm.
b)
The term “chemical fertilizer” refers to any number of synthetic compound substances created specifically to increase crop yield. Some chemical fertilizers, for example, are “nitrogenous” — containing nitrogen — while others are phosphate-based. Other fertilizers are potassium.
c)
Fertilizer adds to the soil’s nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants. While recommended amounts of compost can be quite general, fertilizer application rates are based on the needs of plants. Either organic or conventional fertilizers work well for vegetables, but organic fertilizers have been shown to be friendlier to the soil food web. Chemical fertilizer can also feed composting, but continual use may throw soil chemistry out of balance and discourage microbes.
Compost and organic fertilizers can work together. The organic matter in compost sponges up the fertilizer nutrients until they are needed by plants. Compost also provides many nutrients that plants need in small amounts, such as boron. You can use fertilizer without compost, but why miss an opportunity to increase your soil’s fertility and its ability to hold moisture? Soil that is regularly amended (i.e., improved) with compost becomes wonderfully dark and crumbly and often requires much less fertilizer compared to soil that has not yet benefited from regular helpings of compost.
