suggest any four cropping stages that can be adopted by individuals during old age
Answers
Answer:
Commercially available fertilizers
containing NPK (Nitrogen,
Phosphorus and Potassium) are
globally known to be the "best"
method in agriculture due to its
economic benefits, especially for
farmers and entrepreneurs who
would like to increase crop yields at
the lowest cost possible.
However, from an ecological perspective, the use of artificial fertilizers proves to disrupt the nutrient ratio in soils and lead to the competition of plants in crop lands. This can be considered as one of the main cause of competitive exclusion among vegetation. Furthermore, repeated application may cause toxic buildup of chemicals in soils and may alter the soil pH which can harm beneficial microbial ecosystems.
