how does modern farming practices bring about a conversion of fertile soil barren soil?Explain in detail
Modern farming practices have changed the nutrient management of practice used on farms. Modern farming practices no longer have animals and crops together but are separately practiced.
Modern farming practices depend on synthetic fertilizers. Unfortunately these synthetic fertilizers are over applied to crop land.
Only half of the fertilizers are absorbed by plants and the rest pollute the atmosphere, soils and water ways. Over usage of synthetic fertilizers and manures has lead to nutrient pollution.
Regular usage of synthetic fertilizers and manures causes depletion of organic matter, has adversely affected the soil productivity and overall soil quality. Over usage of synthetic fertilizers and manures has caused the important minerals such as calcium, magnesium and potassium to gradually leach out of the soil.
Heavy metals are added to animal feed in order to increase growth; therefore the manure from these animals contain trace amounts of metals such as arsenic, copper, selenium and zinc which also contaminate soil.
Hence modern farming practices with over usage of synthetic fertilizers and manures have made fertile land to loose its porosity and fertility leading soil erosion making fertile soil unfertile or barren.
