Question

If a farmer plants the same crop in a field year after year , the soil becomes less fertile. What causes this decrease in fertility?

Answer 1

Erosion ? lack of water ? loss of topsoil ? or loss of nutrients ?

Answer 2

i would say loss of nutrients

Answer 3

@miypow is right, but the nutrients lost depend on what is being planted over and over again. If its corn, nitrogen will be lost over the years. Thats why if a farmer wants corn in the same field over and over again he will have some sort of nitrogen enriched seed or fertilizer that he puts in the planter. Have you ever seen a soybean field that has little corn stalks in it? This is because farmers plant soybeans in a field after corn has been there because soybeans put nitrogen back into the soil. Did this help you?
