Major Plant Nutrients

While calcium and phosphorus are often considered the most important minerals among organic and biological gardeners and farmers, we know it’s not that simple. A granite quarry in Madrid province, Spain. All nutrients need to be there in sufficient quantities…

Water

We can’t look at soil management without also looking at water management. This lesson isn’t a complete summary of strategies, but it does cover some of the most important points we need to know. Seedlings in the rain While perhaps…
