Say no to chemical fertilizers now! Modern Agriculture has change into extra dependent on chemical fertilizers for increasing yield of crops. Constant use of chemical compounds has spoilt the land, soil and water. Depletion of soil fertility and high costs of chemical fertilizers has forced many paddy farmers, especially within the delta area, to show in opposition to azolla as an effective bio-fertilizer for their paddy crops.
We will let you know a few paddy farmer Mr. S. Ramuvel in Mayiladuthurai Taluka from Tamil Nadu who’s growing azolla in his box. Azolla is an efficient bio fertilizer for the safety of paddy crops.
Benefits of Azolla:
According to researchers from Tamil Nadu Agricultural University (TNAU), Coimbatore, Tamil Nadu, “Basal application on green azollamanure at the rate of 10-20 tonnes per hectare increases soil nitrogen by 45-60 kg and reduces 20-30 kg of nitrogenous fertilizer requirement of rice crop.”
S. RamuvelFarmers, an organic farmer from Tamil Nadu stated, “Farmers should be made aware of the harmful effects of these chemicals in agriculture and switch over to non-chemical methods of growing crops.”
Azollacan be used as a just right change for urea for paddy vegetation and can be used as a feed for livestock, geese, pigs and fish on account of its high protein content material.
It is eco friendly, non pricey and is helping in safeguarding the soil well being and likewise the standard of crop products.
It may also be transformed to compost via drying underneath coloration and then used like farmyard manure. It is also called a mosquito fern and water velvet.
Azollais a naturally to be had free-floating aquatic fern most commonly present in wet soil, ditches, and pools. Though the fern is broadly cultivated in some Asian international locations akin to Japan, China, Vietnam, and the Philippines, in India it is but to realize extra prominence aside from in some states like Kerala and Orissa.
The fern fixes atmospheric nitrogen into the soil to be made available to vegetation particularly wetland rice crops in the type of soluble nitrogen.
A thick inexperienced mat of azollain the paddy box prevents weed enlargement and is helping paddy growth.
It also prevents water evaporation and increases water use efficiency within the crops.
Mr. Ramuvel mentioned, “When i Used To Be cultivating paddy with chemical fertilizers I needed to spend about Rs.1,500 according to acre. At provide, with azolla, the cost of cultivation has come down by way of 25%. Azolla has greater my paddy yield by 30-40%.”
Farmers can also create their very own nursery for rising this fern, said Mr. Ramuvel. The box should be ploughed, levelled, irrigated, and made to stand within the type of small ponds. Only 15-20 cm of standing water is permitted within the fields. Green azolla at the fee of 20 kg in keeping with hectare, blended with contemporary cow dung must be released into the pond.
Dense Green Mat:
The fern multiplies unexpectedly in about 10-15 days and bureaucracy a dense growth on the surface of the water. It is then harvested the usage of bamboo baskets and launched into the principle field some of the transplanted paddy plants for further multiplication.
Mr. Ramuvel may be promoting the golf green azolla on the price of Rs. 5 per kg to other farmers who do not need a nursery. During summer time azolla is harvested at an interval of 15-20 days and right through monsoon, as soon as a month.
