The Humus is among the richest and darkest of soils. Humus is vital to the growth and health of plants. It brings about balance to the soil and thereby promotes a much healthier plant by increasing the metabolism of a plant root system. Vigorous plants are better able to fight off disease and insects. Humus delivers what we gardeners really want: higher yields and better quality flowers, vegetables and fruits. We produce ditectly in PERU, South America. We export in plastic bags of 40 and 50 kilograms each. Please contact to send you analysis.
