This maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. ... By testing their soil, farmers know which nutrients—and how much—to apply to the soil.

precision farming
British farmers typically use around 2.5 million tonnes of fertilizer annually, primarily nitrogen, phosphorus, and potassium. The amount can vary significantly based on crop type, soil conditions, and farming practices. Recent trends have shown a push towards more sustainable practices, which may lead to a reduction in fertilizer usage over time. Farmers are increasingly adopting precision agriculture techniques to optimize fertilizer application.
More rice has to be grown by farmers.
In lowland areas, farmers typically cultivate rice in flooded fields known as paddies. These paddies are flooded with water to control weeds and pests, and to provide the necessary environment for rice growth. Farmers may also use irrigation systems to supply water to the rice fields if natural water sources are insufficient.

fertilizer
Most crops are grown for profits for farmers, not for personal use. Only in the third world countries like most of Africa and India will you find farmers that grow and harvest rice and wheat for their own use.
