Trace Elements

These are elements, that effect soil fertility but are present in tiny amounts, too small to measure without some very sophisticated equipment. Different trace elements favour different plants. We are still discovering what trace elements do in plants. In many cases they are present in such small amounts, it is hard to determine if they […]

Soil fertility – The NPK group – Nitrogen

Nitrogen To produce leafy growth plants need more nitrogenous compounds. Through photosynthesis they break these down to extract the nitrogen required to create leaf cells. This means they need a compound that is rich in nitrogen. Usually we use urea or ammonium sulphate based fertilisers to increase the nitrogen available for plants. Chicken manure is […]

Fertility and the NPK group – Potassium

Potassium Potassium is generally linked to seed, flowers and fruit production. It is highly soluble and easily leached out of the soil. For this reason is uis more common in sandy soils. Though it is present in manure in small quantities, it is much higher in ash. Primitive cultures discovered that burning off the vegetation […]
