PDC LESSON 4.7 SOIL – PROBLEMS, SIMPLY ADDING HUMUS

 

Most problems with soil are solved by simply adding humus to the soil.

 

Therefore, we are encouraged to grow as much mulch as possible in our garden systems. Grow your mulch where you need it is the catch cry.

Tropical legumes such as pigeon pea, mucuna, lab lab, crotolarias etc. plus all the grass types such as vetiver and lemon grass as well as sugar cane are wonderful sources of mulch material. There is a vast list to choose from in a tropical to sub-tropical climate such as ours. We should be growing plants for mulch all over the place. When a lot of rough mulch is chopped and dropped, manure can also be incorporated into it to speed up the decaying process. 

 

Earthworms are then encouraged to feast on all that raw material; they will multiply and add their worm castings. Earthworms will aerate and mix the soil and, in this way, poorly drained and compacted soils can be brought to life. The minimum amount of organic matter in the form of humus should be at least 10%. With all this organic matter the soil will carry so much life that it simply must improve and become productive.
