Green manure technique:when to sow

The period changes according to the needs. In the case of autumn green manuring, generally, the plants fill a ground otherwise in vegetative rest. The autumn or winter green manure plants are, in fact, slow-growing and will occupy the ground until the spring pre-flowering period.

Green manure plants can also be sown in spring and summer, in the pauses between one flowering and another. If your intent is to prepare a good seedbed, you can choose fast growing green manure plants to sow two months before growing your grower.

When burying green manure plants

To get the maximum benefit from green manuring and to better incorporate the plant mass into the soil, the best time to bury the plant mass occurs when the green manure plants are about to bloom. Generally, with autumn and winter green manure plants, the period coincides with spring, in particular with the months of April and May.

The vegetable mass of green manure plants must be previously mowed or chopped. Before incorporating it into the ground, we recommend waiting a couple of days so as to partially dehydrate the green part. If you bury too fresh cut grass, you risk undergoing fermentation processes that hinder the decomposition of plant biomass.

The vegetable mass must not be buried deeply: it is sufficient to incorporate the grass clippings to a depth of 10 - 15 cm. If buried deeper, due to poor oxygenation of the deeper layers of the soil, there may be problems with decomposition with insufficient humus formation. .
