ORGANIC GARDENING: LIEBIG’S LAW OF THE MINIMUM

January 17, 2017 4:47 pm Published by Leave your thoughts

When growing organically it is important to understand Liebig’s law of the minimum.  Originally developed by Carl Sprengel in 1828, Justus Von Liebig’s law essentially states that growth in plants is not controlled by all available nutrients but is controlled by the nutrient it has least available to it.

What does this mean for the organic gardener?

Simply put, the plant needs all the macro and micro nutrients available to it during its entire life cycle.  It’s entire life cycle.  In some sectors of the agricultural industry, namely the hydroponic market, companies market product of increased NPK for different phases of the plant’s life cycle.  For example, a ‘bloom booster’ is marketed for the plants fruiting/flowering phase, but, biologically speaking following Liebig’s law, the plant does not need an increase of phosphorous if all nutrients are available to it in the proper amounts.

So, when organic gardening it is important to build your own soil.  When you build your own soil you are able to control everything that goes into it.  By building a soil that provides everything a plant needs for its entire life-cycle, you will never have to ‘feed’ your plants bottled nutrients or the like to have a productive life cycle.

To build a proper organic soil, please check out our other blog posts about No Till Recyclable soil.

For the recipe and ease of use, we have provided it here below:

Organic No-Till, Recyclable Living Soil

Equal parts aeration, compost and peat moss.
For every 1 cubic foot of dry soil, add:
1/2 Cup Neem Meal
1/2 Cup Kelp Meal
1/2 Cup Crab Meal

4 Cups of Rock Minerals
-1x Bentonite Clay
-1x Oyster Shell Powder
-1x Basalt
-4x Glacial Rock Dust

Keep soil moist at all times.  Apply enzyme teas 2x a week and botanical teas 1x a week.  If soil dries out, add an actively aerated compost tea.
