How to grow beans in a biological way
To understand how to grow beans in a biological way it must meanwhile know that these are divided into two groups: those where you eat the seed (real beans) and those where you eat everything (called green beans). The cultivation techniques are very similar but in this contribution we will talk about the cultivation of real beans.
In turn, the beans are divided into two types: a definite growth (dwarf) and indeterminate (climbing). The cultivation of beans becomes important as well as for the contribution of proteins to the nitrifying function of the soil. It must be said that they are plants that prefer warm and temperate climates and with good exposure to the sun. It prefers medium-textured soils, sub-acids but it adapts very well even to different soil conditions.
The recommended sowing time of the beans is before the beginning of May (until the whole summer period), with very shallow seed placement (at a depth of 1.5 times the size of the seed). You can opt for the preparation of a seedbed in order to anticipate the harvest time slightly at the time of sowing. In the lunar calendar the best time for sowing is two or three days after the first lunar quarter and always in the crescent moon. Obviously for the climbing species it is necessary to provide supports. In the best vegetable gardens is the association of the bean with: basil, cabbage, cucumber, lettuce, aubergines, potatoes, tomatoes, turnips, radishes, celery and courgettes. The two associated crops benefit each other.
For the fertilization of beans, the organic fertilizer with mature manure or compost and in non-alkaline soils with the addition of wood ash or vegetable parts is good. The intake of nitric nitrogen must absolutely be avoided.
To have a good production you must never miss the water especially after flowering and make continuous weeding to eliminate the competition of weeds. The mulching technique with straw or other plant residues solves the necessity of the weeding at one time and contributes to a considerable reduction in irrigation. However, the climbing varieties require more water; while especially for the dwarf must be performed the tamping (to operate with dry soil) that helps it to be more sustained.
For harvesting this must be done when the pod is completely colored with a tendency already to dry. On average, the bean culture cycle can fluctuate (depending on the season and the variety) between 80 and 120 days.
Among the adversities in the field above all aphids and radical rots are remembered. For the aphids are excellent treatments with Marseilles soap, while for the rot the mulch technique is optimal.
Since beans can be preserved and consumed even by pests in the open field, we must add the weevil; a small beetle whose larvae winter in the seeds, eroding them and emptying them. Among the prevention techniques of this parasite you can pass the seeds a few minutes in the microwave killing any insects present.
