The description of action of preparation TERAVET is provided in this article on productivity and quality of grapes. This polymeric connection on the basis of potassium is good absorbent and is used at cultivation of a number of agricultural cultures in a droughty zone of Ukraine.
Huge value of soil moisture for agricultural industry started to be realized by the person since then as he started to be engaged in agriculture.
In different conditions grapes spend moisture from 100 to 140 m3nagektar a vineyard, the consumption of water on 1 hectare of a vineyard reaches 1100 mm for the vegetative period – from blooming of kidneys to a leaf fall (within 207 days) one bush allocates 4,11 l of water that corresponds 4245 m3 on 1 hectare (the 5000th bush/hectare) in the conditions of subtropics.
For the South of Ukraine the volume vlagozapasov in the soil makes 1850-2100 m3/hectares.
The grape bush receives moisture from the soil, or in the form of water vapor from air. The content of water in the soil depends on an amount of precipitation, and also from water-retaining ability of the soil which often happens quite low. This problem is solved by means of artificial absorbent – TERAVET.
Terawet superabsorbent – polymeric connection on the basis of potassium is made next amount of crystallization: T – 100 – small granules for friable soils and preparation of enveloping pastes. T – 400 – AgraWet – a combination of the various sizes of granules for the general using.
At hit on damp Wednesday of a granule bulk up the gelevidny weight is formed. It is caused by the main Terawet property – to absorb and hold in a polymeric chain a water large quantity: 1 kg of dry granules absorbs to 400 l of water with all nutrients dissolved in it. At approach of the droughty period the root system of a plant takes amount of moisture necessary for it, the granule decreases, coming back to the initial size and is ready to a new cycle of accumulation.
Properties of preparations of absorbents it is similar to special group of plants – kserofitov (vegetation of dry zones of dwelling), adapted for long droughts – to succulents – plants with fleshy stalk and leaves which reserve water during a season of rains and spend during a drought.
Experience 1. In the first year of research after January frosts (2006 g) experiment on AF "Magarach" vineyards (Vilino’s page) consisted in studying of a surface of a fructifying bush, when entering into a zone of a zaleganiye of roots of 4 and 8 pieces of tablets.
Entering of a preparation into a zone of a zaleganiye of the main roots on a fructifying vineyard made positive impact on growth, development and productivity of grape bushes. Bushes under which TERAWET was brought differed stronger gain – 43,7 and 48,4 m, whereas in control – 40,1 m. The average length of escape increased by 5,2-7,1 % in comparison with control also.
The average mass of a cluster changes depending on number of introduction of a preparation by experience options. At identical loading of bushes average mass of a cluster in option with preparation introduction sostavilf 172,8 and 180,7 g that for 6,2-10,3 % are higher, than in control. Application of a preparation allowed to raise a crop in option with introduction of 8 tablets "TERAWET" for 24,1 % (with 2,2 to 2,9 kg from a bush). Sugar content of juice of berries in all options with application of a preparation was for 0,3-1,0 % more than in control. The maximum sakharonakopleniye is noted also on bushes with option of introduction of 8 tablets of a preparation (19,5 g/100 of cm3).

Experience 2. Experiment in landing of a young vineyard, on Cabernet grade Sauvignon in JSC Kachinsky + economy was the same year made. Improvement of a prizhivayemost of bushes depending on options of introduction of a preparation of "TERAWET" was noted. The Prizhivayemost in control in 70 days after landing made 81, 2 %, and in options with preparation introduction – 84,4; 91,4 and 98,3 % respectively. The greatest indicator of a prizhivayemost was in introduction option under a bush of 5 g of granules of "TERAWET". Studying of rostovy processes showed that application of a preparation increased an indicator of average length of escape – by 10,9-18,0 %, extent of ripening of escapes for 10,7-16,1 %, the area of a sheet surface – for 3,4-21,0 %. The Prizhivayemost at the end of vegetation in skilled options for 7,8-20,7 % was higher, than in control.
Rostovye processes, Cabernet Sauvignon grade, (young vineyard), 2006.
Studying of postactions of application of a preparation of "TERAWET" in all options of experience showed its positive influence on development of a grape plant. The option with introduction of 8 tablets "TERAWET" under a bush appeared the most effective on a fructifying vineyard.
Postaction of application of a preparation on grapes development, a grade to Aligota, (a fructifying vineyard), 2007.
In view of a positive effect from application of a preparation of "Teravet" as when landing young vineyards and a garden, and also at introduction under a fructifying vineyard, consider expedient to recommend when landing young vineyards and gardens to agricultural enterprises of Ukraine.
