Question

Rice farming practiced over a long period of time may have exerted some impact on the decrease in the total phosphorus concentration

Answer 1

Intensive farming involves various types of agriculture with higher levels of input and output per cubic unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour, and higher crop yields per cubic unit land area.[1][2]This contrasts with traditional agriculture, in which the inputs per unit land are lower. The term "intensive" involves various meanings, some of which refer to organic farmingmethods (such as biointensive agriculture and French intensive gardening), and others that refer to nonorganic and industrial methods.
