Many gardeners wish to enrich their soil with organic material, but it is not possible to set up a composter. Usually, they are not allowed by the lack of time or the lack of free space in the garden. Often, getting manure turns out to be difficult and expensive. Green manure is the solution to similar problems, which we sow in empty places on the beds and dug with soil two or three weeks before sowing or planting new plants. Therefore, a small packet of seeds is enough, to obtain valuable organic material that enriches the soil.
Choosing green fertilizer
The choice of plants for green manure depends on this, whether we will grow them in the main crop, as catch crops or catch crops (summer or winter), as well as soil type and species, what we intend to grow on them later. The only really effective way is to experiment with different plants and observe them, at what date after sowing can they be dug with soil (zazwyczaj jeszcze przed okresem kwitnienia). If we want to increase the amount of nitrogen in the soil, Legumes will be suitable.
Advantages of green fertilizers
• Compact field of plants grown for green manure protects the soil against erosion, inhibits the growth of weeds and limits excessive water evaporation. The deep and branched root system of these plants also contributes to the loosening of the soil and the mobilization of hard-to-reach phosphorus and potassium compounds from its deeper layers. If we grow legumes for green manure, e.g.. clover or lupine, so we enrich the soil with nitrogen as well. Species from this family live in symbiosis with papillary bacteria that bind free nitrogen from the air, used by crops to build the body, which later do not require nitrogen fertilization. Moreover, they store it in the soil also for successive crops. Let us not forget about that as well, that mastic plants are a real paradise for beneficial insects and frogs that eat snails.
Recipe for green manure:
1. We sow plants for green manure in empty places on the bed.
2. When the plants are of sufficient height, we trim or trim them, swath for compost.
3. We dig the rest with the soil in two, three weeks before planting or sowing new plants.
The soil immediately after digging with green manure may not be the best substrate. Some green fertilizers may release substances that inhibit sprouting at the initial stage of decomposition. It is therefore much safer to hold off sowing for a month or so, and even better, instead of sowing, plant young plants in this place.
