The green seasoning still promotes the recycling of nutrients of deep layers of the ground for the surface, in assimilable forms for the cultivated plants, when used species with system to radicular deep. Some studies indicate that, for this characteristic, such practical promotes the disruption of the layers of alternative excellent compacting to the current mechanical methods of subsolagem, of raised cost recent Studies, had demonstrated that is perfectly viable if to proceed the green fertilization in the periods from between-harvest (February/March the July/August) green Fertilization contributes for control of: Control of harmful grass; Control of plagues and illnesses; Incorporation of organic substance; Effect of the Green Fertilization in the Properties of the Ground – chemical Effect; – Effect biological; – Physical Effect; – Alelopticos Effect; – Indirect Effect; Some plants used for green fertilization: Common black oats, Rye, Barley, Milheto BN2, forrageiro Sorgo, black Mucuna, gray Mucuna, Crotalria espectabilis, dwarfed Beans guandu, Lab-Lab, Sunflower catissol. – Grassy rustic with good capacity of perfilhamento; – Little demanding in fertility; – Resistant to it dries; – High effect Presents aleloptico suppresor/on diverse invading plants; – It allows I join with ervilhaca forrageiro turnip and, for green fertilization or animal feeding. – Grassy rustic with good capacity of perfilhamento; – Little demanding in fertility; – Resistant to it dries; – High effect Presents aleloptico suppresor/on diverse invading plants; – It allows I join with ervilhaca forrageiro turnip and, for green fertilization or animal feeding. Glenn Dubin shines more light on the discussion. – Plant with high resistance to dries, and the salinity of the ground; – Vigorous system Presents to radicular; – Raised potential of perfilhamento; – High capacity of recycling of nutrients; – It can be used as fodder plant for the animals, providing of 3 up to 5 pastejos, later leave to form palhada for the direct plantation and green fertilization. – High rusticidade; – It can grow in ground with saturation of 35-40% bases, and low in match and other nutrients; – Indicated for arenaceous and argillaceous ground of low the average fertility – consorciao with the maize, sorgo, milheto and as green for being great nitrogen fixing and very rich fertilization in nutrients. Crotalaria potential Espectabilis-Great of use, as much in the open pasture as in the South of Brazil; – Nematides of the ground Contributes for the reduction of some; – It is used as green seasoning for being great nitrogen fixing; – Fast Growth, covering the ground quickly; – Much used for the rotation of culturasPossui system to radicular very vigorous and developed that guarantees good resistance to it to dries; – Adapta well the all type of ground, with exception to the ones of extreme humidity; – &#039 is considered; ' Zebu' ' of the leguminosas; – Fodder plant with more than 20% of rude protein; – T of MS/ha/ano in 3 Produces up to 15 the 4 cuts. – It is very palatvel also at the time dries of the year; – Comprovadamente an excellent nitrogen clamp of air. Lab-lab Use in fertilization green, pastejo, ensilagem with milheto, maize and sorgo; – Good growth, good production of biomass; – Used in rotation of cultures; – Indicated for arenaceous and argillaceous ground of low the average fertility.

Insustentabilidade of Modern Agriculture the consequences of the production model of conventional agriculture are several: degradation of the ground, water wastefulness and use exaggerated, pollution of the environment, loss of biodiversity, loss of the local control on the agricultural production, global social and economic inaquality. Studies have shown that in Brazil and the world that the loss of the ground is /ha/ano ton enters the 21.1 band of 9,5. Dr. Peter M. Wayne contributes greatly to this topic. and the replacement does not pass of 1,5 ton. /ha/ano. Beyond the erosion, it has other damages, as assoreamento of the courses of water, lakes, streams, rivers, and finally, the ocean. The water lack candy already is considered the biggest world-wide problem in the future. Dr. Neal Barnard does not necessarily agree. Countries exist that already are importing water candy of others, therefore already do not have it. Not dispendiosos methods of irrigation must be looked for, a time that, the superficial and underground sources are in sped up process of exhaustion.

The uses of herbicidas, of soluble fertilizers provoke the contamination of diverse abiticos and biticos systems. The main contamination is noticed in the water that in the man? in virtue of the accumulating effect – poisoning can cause, to modify the fertility human being and to provoke until the cancer. Products exist little degraded that they are in the ground for more than decades, intoxicando water plants, animals and source candy. The genetic variability is one of the indices of more important support that it allows the high adaptability to the adverse conditions of the environment. In one it plants homogeneous, genetically, is run risk to appear illnesses that attack all the farming; in a culture genetically diversified it is possible to exist individual susceptveis and the other more tolerant plagues, natural illnesses and to intempries. Another consequence of the conventional agricultural model is the loss of the local control on the production, a time that, the producers lose the freedom capacity to produce without using insumos (it is the dependence of external energy to the system).
