They convert free nitrogen and exude nitrogenous compounds into cavities of the leaves. It gives high yield when mixed with chemical fertilizers.Ĭyanobacterium can fix nitrogen hence act as bio-fertilizers.Īzolla is a floating fern, leaves show cavities in which Anabaena is found. Simple seed inoculation with this bacterium increases the dry weight of cereals.

LOOSE ASSOCIATION OF NITROGEN FIXING BACTERIAĪzospirillum has been isolated from the roots of grasses, rice and maize. This is utilised by crops like cereals, millets, fruits etc. The non leguminous plants are Casuarina, Myrica, Rubus and Alnus.Īzotobacter fixes free nitrogen of the air. The legume crops are thus used in crop rotation and green manuring.įrankia is a nitrogen fixing bacteria living in symbiotic association with non leguminous plants. Thus the succeeding crop requires less nitrogenous fertilizers. This enriches the soil with nitrogen compounds. They fix atmospheric nitrogen in the presence of a pigment leghemoglobin.Īfter harvesting the crop, the roots of legume crops are allowed to decay in the soil. It forms root nodules in the legume plants and fixes atmospheric nitrogen. Rhizobium is a symbiotic bacteria living in association with leguminous plants. They enrich the soil by fixing free nitrogen into nitrogen compounds and thus reduce the dependence on the use of chemical fertilizers. It takes about 4-6 months to form compost manure.īacteria that improve soil fertility may be symbiotic, non symbiotic (free living) or occurring in loose association with roots of higher plants. It is prepared by dumping these substances in heaps with sprinkling of chemical fertilizers like ammonium sulphate, superphosphate etc. It consists of rotten vegetables, animal refuse, groundnut husk and other substances. Residue of gobar gas plant is a kind of farmyard manure. It enriches the soil with many organic substances and releases mineral element in the soil. Manure consists of colloidal particles that help to imbibe water and loosen the soil, increase its aeration and permit easy penetration of roots in the soil. It is obtained by partial decay of animal dung, farm refuse and crop residues. It also provides a protective action against erosion and leaching.Ĭrops like cluster beans ( Cyamopsis tetragonoloba), horse gram ( Macrotyloma uniforma), lentil or masur ( Lens esculenta) etc., are grown as green manure crops. This supplies the soil with organic as well as inorganic components to the soil. Quick growing leguminous crops are grown and ploughed when they are about one foot in height. They also add to water holding capacity of soil.

Manures supply all essential elements required by the crop plants. Please note all warning notices and symbols in the instructions for use.Manures are organic wastes that after partial decay are added to the soil to increase crop productivity. Before use read the label and product information. This is solely a product information but not a substitute for observing instructions for use. In addition, new pictograms bring all product advantages to the point. For more authenticity and a more natural look, illustrations in a delicate watercolor look are now used on the labels instead of color-intensive cut-out images. Doing so, COMPO creates a modern look and at the same time creates recognition value for existing customers. It combines essential elements of the well-known COMPO BIO sub-brand with new accents. The revised packaging design is primarily intended to appeal to a younger, environmentally conscious target group. Thus, it helps both diy stores and garden centers as well as consumers to get a fast overview on how and where to use the products. At the same time, the areas of application, target crops and pests on the packaging are moving more clearly into focus. The herbal active ingredients such as rapeseed and orange oil, neem or natural pyrethrum form the communicative focus.
