Since your soil affects how well nutrients and water are retained in the soil, it’s important to understand the soil texture and pH of your soil. Clay and organic soils hold nutrients and water much better than sandy soils. As water drains

Clay and humus keep water and plant nutrients in the soil. Sand will hold only a little water in the soil. If the soil has too much sand, the water will flow down into the earth. The water that flows down takes plant nutrients down too. The plant roots can not get at the water and plant nutrients if they go too deep.

To supply nutrients for plant production, properly utilize manure or organic by-products as a plant nutrient source, minimize agricultural non-point source pollution of surface and ground water

CROP NUTRITION Scott Black and Graeme Batten The root surface contacts nutrients in the soil solution through: • mass flow of soil solution to the root, largely driven by extraction of water from the soil by roots to balance losses due to transpiration in the shoots of the plant. The resulting water potential gradient conveys water and the nutrients it contains towards the root 7 PLANT NUTRIENTS 61 Plant nutrients All plants require nutrients to survive and grow. Plants take nutrients from the air, the soil, and the water. Because you cannot see nutrients — they are colourless gases or are like dust dissolved in water or stuck onto each piece of soil — it is sometimes hard to under-stand how they work.

(1993) in the study on rates of soil nutrient depletion in sub-Sahara Africa (SSA). The nutrient budgeting approach was used by Stoorvogel et al. soil pH 6.0-7.5 is acceptable for most plants as most nutrients become available in this pH range. Soil pH is important because it affects the availability of nutrients to plants. Nitrogen, phosphorus, and potassium are the primary nutrients needed in fairly large quantities. Calcium, magnesium, and sulfur are secondary nutrients required

Soil and Soil Nutrients Soil Texture In general, most plants grow by absorbing nutrients from the soil. Since your soil affects how well nutrients and water are retained in the soil, it’s important to understand the soil texture and pH of your soil. Clay and organic soils hold nutrients and water much better than sandy soils. As water drains nutrients. Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil. An appropriate balance between soil air and soil water must be maintained since soil air is displaced by soil water. Achieving Balanced Nutrition Several nutrients compete with each other over uptake by the plant, so keeping

soil nutrients (i.e., In 1-5 and Out 1-5) requires different approaches, as defined by Stoorvogel and Smaling (1990 and 1993) and Stoorvogel et al. (1993) in the study on rates of soil nutrient depletion in sub-Sahara Africa (SSA). The nutrient budgeting approach was used by Stoorvogel et al. these nutrients from the soil. First, the soil must be sufficiently moist to allow the roots to take up and transport the nutrients. Sometimes correcting improper watering strategies will eliminate nutrient deficiency symptoms. Second, the pH of the soil must be within a certain range for nutrients to be release-able from the soil particles
