Soil Fertility

Role of green manures in soil fertility

Nitrogen is an essential nutrient needed by plants but which is easily lost when the soil is poorly managed. In sustainable agriculture, green manure or cover crops play a major role in improving soil fertility and farm productivity.

Use earthworms to improve soil fertility

Compost making is important in any organic farm. Farmers can improve the quality of the compost they make using earthworms which help produce high quality compost that has more nutrients than ordinary compost to nourish crops and enable them to grow well.

Compost making should be a continuous process

Farmers can help restore and build soil fertility in their farms if they can make compost preparation an integral part of their farming. In an organic farming system, compost is never enough. It is a continour process for soil improvement.

Organic fertilizers have many benefits to your crops

It is time for planting again and farmers are struggling to buy inputs for use in planting maize, beans and other crops. Apart from seeds, the other most important input is fertilizer. Of course, many farmers planting maize will buy Diammonium Phosphate (DAP).

Tithonia can improve soil fertility on the farm

One of the major problems facing crop production in Kenya is declining soil fertility. According to Ms. Mary Gathara, a research scientist at the Kenya Forestry Research Institute (KEFRI) Soil Chemistry Department, many Kenyan soils are deficient in nitrogen and phosphorous.
