2.1 Soil
The soil is a major source and natural medium for plant growth which has a direct impact on yield and quality of crops growing on it.
2.1.1 Nutrients in soil
Most plants raise by absorbing nutrients from the soil. Soil is a major source of nutrients needed by plants for growth and development. There are two main classification of nutrients in the soil; Macronutrients and Micronutrients.
Carbon (C), Hydrogen (H), and Oxygen (O) are also essential for plant growth, but not considered as soil nutrient because these taken from the air and in water. (Vinegrowing)
Plant roots include definite conditions to achieve these nutrients from the soil. First, the soil must be sufficiently moist to let the roots to adopt and transfer the nutrients.

Classifying and preventing plant from soil nutrient deficiencies and toxicities is an significant part of planting or farming. Nutrient deficiency occurs when an essential element is insufficient to meet the necessity of the growing plant. The symptoms of Nutrient deficiencies and toxicities can be seen first in the leaves, this depends on the mobility of the nutrient. Deficiencies are first seen in older leaves for mobile nutrients (N, P, K and Mg) while deficiencies for immobile nutrients (Ca, B, Cu, Zn and Fe) are first seen in youngest leaves and/or growing tissue. (Nutrient and Physiological …show more content…
Plants absorbed large amounts of potassium. It is used to build proteins; increases cuticle (waxy layer) to inhibit water loss; increases resistance to disease by strengthening stalks and stems; helps prevent sagging; and improves flavor, texture, fruit size, and fruit improvement. The existence of clay in the soil increases the amount of potassium present. The amount of potassium necessary in soil depends on the crop. Potassium can be added to soil thru fertilizers and organic material. Potassium deficiency is also known as potash deficiency. (Soil Macronutrient
