activity, organic matter, and plant nutrients— all key components of healthy soil. The on-site loss of this upper layer of soil nearly eliminates the soil’s natural ability to provide nutrients, regulate water flow, and combat pests and disease. !"Loss of nutrients and nutrient holding capacity, results in a less fertile
nutrient is supplied to the root surface at a concentration high enough to meet the demands of nutrient uptake, the demands of growth and development will normally be met. For example, the ratio of calcium and magnesium on the soil cation exchange sites and in soil solution has little effect on the ratio of these nutrients in the plant.

vegetables, for example, come packed with vitamin C, a nutrient that helps maintain the strength of your blood vessels. In contrast, an unhealthy diet rich in saturated fat and trans fat (as opposed to healthy fats like the type found in nuts, avocado and olive oil) increases your blood cholesterol, which threatens your cardiovascular heath.

It is now known that this abiotic factor (soil) is not essential as such for plant growth. Rather, it is the nutrients that are present in the soil that make plants grow and enable them to complete their life cycle. Climate The climatic factors which affect plant growth include: Humidity Aeration Light Temperature
nutrient environment of the open ocean. O 2 cycling around the pho-tosystems does not change the fun-damental operation of light energy harvesting and carﬁ xation; its importance lies mainly in enabling phytoplankton to adapt to variable light environments. However, these seemingly minor molecular-scale changes can also have implications

levels of anthocyanin (a purple colored pigment) that can accumulate when plant functions are disrupted or stressed. This symptom can be particularly difficult to diagnose because cool temperatures, disease, drought, and even maturation of some plants can also cause anthocyanin to accumulate (Bennett, 1994). Certain plant cultivars
