- During planting, fertilizer is applied below the soil surface close to the seed row.
- Often, the fertilizer is placed 1 to 2 inches below (or below and to the side) of the seed row.
- In cool, wet areas, a “starter application” of fertilizer is placed in a subsurface band to boost seedling growth.

Why is fertilizer important?
Use of Fertilizers or Importance of Fertilizers in Agriculture. Unlike manures, fertilizers are very expensive and are used in large amounts in farming fields. As a part of crop production management, farmers largely depend on fertilizer. But they should only be used when it’s necessary.
What is fertilizer?
Fertilizers are compounds which promote plants growth. There are two types of fertilizers – organic and inorganic. Fertilizers provide the plant with the required nutrient. Pesticides are the substance designed for preventing, destroying, repelling or reducing the pests which are the major cause for the damage of the crops.
What is manure fertilizer?
Fertilizers are commercial products available in different forms like solid, gas or liquid. Both manure and fertilizers contain salts and organic chemicals which consist of essential plant nutrients such as nitrogen, potassium, phosphorus in known concentrations. They make soil fertile and provide nutrients to plants for better growth and higher yield.
What is chemical fertilizer?
Chemical fertilizers are considered inorganic fertilizers containing a high concentration of nutrients required for plant growth. They are composed of primary macronutrients, like nitrogen, phosphorus, and potassium compounds. Based on their composition, chemical fertilizers are further divided into different types.
What is the difference between fertilizer and pesticide?
Fertilizers provide the plant with the required nutrient. Pesticides are the substance designed for preventing, destroying, repelling or reducing the pests which are the major cause for the damage of the crops. These substances include both chemical substance and biological agents.
Why do living organisms need nutrients?
Every living organism requires nutrients for their growth and other metabolic activities. For their survival, they follow a mode of nutrition. We humans and animals depend on plants for nutrients. Plants have an autotrophic mode of nutrition where they prepare their own food and obtain their nutrients via photosynthesis.
Do plants need nutrients?
Plants have an autotrophic mode of nutrition where they prepare their own food and obtain their nutrients via photosynthesis. The soil is not fertile enough to provide essential macro and micronutrients to plants in sufficient quantity. Hence they need another source of nutrition.
