Fertilizer uptake by irrigated plants is influenced considerably by fertilizer placement and timing and by water application methods. Because some fertilizer elements move with water in the soil, these plant nutrients must remain or arrive within the sphere of the plant roots after fertilizer and water are applied. The goal is to develop cultural practices by which crop nutrient needs are satisfied by maximum uptake from a minimum quantity of applied fertilizer.
