With respect to the following statements, choose the correct answer.
i. Food security depends on both, the availability of food and access to it.
ii. Mixed farming degrades the nutrient quality of the soil.
iii. Fertilizers are commercially produced plant nutrients.
Fertilizer
Food security depends upon both, the availability of food and access to it. Just over production does not guarantee food security. People should have money to buy food for themselves. Mixed farming involves the growth of multiple plants simultaneously on the same field. This increases the quality of soil if leguminous plants are grown along with crops. Fertilizers, like urea, are commercially produced plant nutrients.
