 Crotalaria juncea in addition to the high biomass also has a high nitrogen content also (3.01% N). This plant is very soft and suitable for use as green manure utuk. In the past crops are always planted after harvesting is completed.
Actually the use of green manure is not new anymore, but because so many have been abandoned by farmers, the green manure has been abandoned. For example, in the seventies, is a must the tobacco plant in Klaten, plant Crotalaria juncea (snore-snore) on tobacco after each harvest, aiming to restore and improve soil fertility. Once harvested tobacco, planted snore-snore, after a big snore-snore then the plant was torn down and mixed with soil during land preparation (piracy) are then pooled. But in the present imperative is difficult to be fulfilled either by the factory owners and farmers. Farmers have objections if the fields planted with legumes (snore-snore), it is considered not productive, long-snore snore planting (about one month). |

Green manure  Green manure is an organic fertilizer derived from plants or in the form of residual crop. This plant material can be immersed in the green or the time after composted.
The benefits of green manure:
Increasing the organic content and nutrients in the soil resulting in improved physical, chemical, and biological land, which in turn impact on increasing the productivity of soil erosion and soil resistance.
Source of green manure:
Source of green manure can be either the remnants of the plant (the remaining harvest) or plants grown specifically as a producer of green manure or derived from wild plants.
Plant species used as the preferred source of green manure legume species, because these plants contain a relatively high nutrients (especially N) compared with other crops, legume crops are also relatively easy to decompose so that the provision haranya be faster.
1. Remaining plants
Crop residues (waste harvest) is the most economical source of BO because this material is a byproduct of farming activities, so it does not cost money to purchase. Haranya content of crop residues, although relatively low, but because the total crop residues generated each harvest season a lot, so the total donated nutrients from each harvest season is no less compared legume types. |
