From dry and / or irrigated grasslands, through mixtures of seeds selected for their perfect adaptation, composed of grasses and legumes, determined by the following factors: soil type, climatology and utilization.
The correct choice of the mixture is fundamental to the success of the prairie.
The revaluation of the trophy concept has a redoubled importance nowadays, and hunting activity is assuming an increasing importance in the economy of many farms. Today the preservation of species and the conservation of nature is evident. The growing professionalization of this sector allows the big game to find new solutions that give it a prominent position in the hunting area, either in quantity and quality of the trophies obtained, or in the reduction of the inherent costs of these. Extensive hunting is all the more profitable with better exploitation of grazing food resources. Knowing the importance of pastures in most hunting operations, the EXTENSIVE range (long-term dryland meadows) has been developed, with a productive capacity of 3 to 6 times that of natural pastures. EXTENSIVE is a range of mixtures composed of leguminous plants (annual and perennial) selected for their perfect adaptation to specific conditions of soil and climate. When well installed and managed they produce very productive and persistent meadows, of excellent quality and low cost, improving the profitability of hunting activity.
Impact of EXTENSIVE on hunting production:
- Increases grass production for many years.
- It significantly improves the economy of farm operations.
- Allows higher animal loads per ha.
- It increases the percentage of females that are covered at two years of age, this percentage being higher with the better the body condition of the animal.
- It increases the quantity and quality of the trophies obtained, and reduces the costs inherent in obtaining them.
Impact of EXTENSIVE on the environment:
- It guarantees a high biological fixation rate of Nitrogen.
- It improves soil fertility by increasing organic matter.
- It increases the capacity of infiltration and water retention of the soil.
- It reduces soil erosion.
Its production is between Autumn and Spring, depending on the rainy season, however, it can be grazed throughout the year. In the wet period, the animals use the high quality green pasture, and during the Summer the leaves and dry stalks, as well as the seeds, constitute a valuable food reserve of high nutritional value and much appreciated by the animals. The seeds of the different legumes of the EXTENSIVE range are inoculated with Rhizobium, guaranteeing high rates of fixation of atmospheric nitrogen.
- Preparation of the soil: it must be done so that the surface layer has a minimum thickness of 10cm, is well broken-down and relatively flat.
- Time: from September to October, as early as possible.
- Density: 25 to 30 kg / ha.
- Depth: the seed should be buried to a maximum depth of 0.5 to 1.0 cm, as the soil must be compacted after sowing. A spiked curl or alternatively a tier of spikes should be used to incorporate the seed superficially and leave the soil well compacted.
- Nitrogen: only in late plantings 20 to 40 uds / ha of N.
- Phosphorus: 60 to 90 units / ha P2O5
- Potash: 60 to 90 units / ha K2O
* Fertilization should be conducted consicering the soil analysis.
At the end of the summer, and preferably having dried well, the dry grass must be treated with 20 to 30 units of phosphorus (P2O5) and, if necessary, also potash. It is important to perform this maintenance fertilization every year, at least until a reasonable level of nutrients in the soil is established. Soil analysis every 3 years is recommended. We do not recommend the use of nitrogenous fertilizers, since the legumes present in the prairie can fix 100 to 200 kg / ha / year of atmospheric nitrogen.
HANDLING AND USE
In the first year the main objective of the management of a permanent meadow is to guarantee a large production of seeds (seed bank) of the species and varieties that have been planted, to guarantee a long duration and excellent productivity. To this end, it is necessary to focus efforts on planting and management that favors abundant seed production. The sowing should be done in a timely manner (with the soil still somewhat warm) and on properly prepared and fertilized soil.
