Soil Fertility
Bayani Gaba-gaba
A fertile soil is one that can supply a crop with the nutrients it needs, in the right amounts, throughout the growing season. Fertility is not the same as the amount of soil there is: a deep soil can still be hungry, and a thin soil can be made productive with care. The skill of the farmer lies in reading the signs of what a soil lacks and putting it right, whether by recycling nutrients naturally or by adding the right fertiliser.
In this lesson you will learn the major plant nutrients and how to recognise their deficiency in a crop, follow nitrogen as it cycles between the air, the soil and living things, and weigh the value of legumes, organic manures and inorganic fertilisers. You will also see how testing and adjusting soil pH, by liming or by choosing fertilisers with care, keeps a soil in good heart.
Manufura
- (a) explain the importance of the following major nutrients to soil fertility and describe the signs and effects of their deficiency in plants: major nutrients - compounds of nitrogen, phosphorus, potassium, calcium, magnesium and sulfur.
- (b) carry out practical soil sampling and tests for soil pH.
- (c) describe the nitrogen cycle and its importance to soil fertility.
- (d) explain the importance of legumes and the use of organic fertilisers (manure and compost) in maintaining good soil structure and fertility.
- (e) describe the use of inorganic fertilisers (limited to one example each of a fertiliser containing predominantly phosphorus and predominantly potassium and one example of a compound fertiliser) in maintaining soil fertility.
- (f) explain how fertilising practices and liming can affect soil pH.
