There are many potential ways to reduce the amount of inorganic fertilizer that is applied to cropland. If you were to make recommendations on the use of inorganic fertilizer application to a crop, what are some of the variables and processes you would consider?
What will be an ideal response?
One of the first considerations is the particular nutrient needs that maximize a particular species
growth. Fertilizers have various amounts of nitrogen, phosphorous and potassium well as other
macro- and micronutrients. Matching fertilizer to plant growth is obviously important. Different soil
types maximize growth of different species. Knowing the relative proportions of different soil
components and the farming practices that maintain those proportions would aid in reducing amounts
of additional fertilizer a soil requires as well as the amount of irrigation required. Growing crops in
regions where soil characteristics already match plant requirements is key to reducing the need for
inorganic fertilizers. Practices that promote mycorrhizal associations, as well as manipulating both
plant and fungal genes to increase transport and uptake of ions has lots of potential. Likewise, research
in promoting nodule formation in N-fixing crops such as soybean reduces fertilizer loads.
