In the knowledge of the present invention the proper selection of the cultivating conditions belongs to the obligatory skill of the man skilled in the art. As a general rule it can be stated that for the same plant cultures generally identical methods of treatment are to be applied.
  • the preparation and use of the compositions of the present invention represents just a very small part of the total cultivation costs and that the results obtained ensure an efficiency being at least five to ten times higher than the expenditure, the use of the composition of the present invention does not involve any significant risks.

  • the composition of the present invention is formulated in powder form which can be converted into a solution or suspension having the desired concentration at the spot of application. If the composition of the present invention is to be applied to a plant protecting agent, the finely ground herbicidal or insecticidal agents may be added to the liquid composition. In an alternative manner the composition may also be admixed with the ready-for-use plant protecting agent.

  • Composition A is flown through the filled tubes in doses according to Table 1. The rate of capillary water-raising is determined after 5 and 24 hours, respectively.
  • Water-raising data of the loam show a decreasing tendency is similarly to the results obtained with sand. On clay the increase of the dose results in an increase of capillary water-raising.
  • the differentiated porosity and pore volume are studied under freeland conditions on sand plots having a size of 0.5 ha.
  • a dosage range of 1.6-3.2-6.4-12.8 x 10 -3 kg/to the best results are obtained by using a dosage of 6.4. x 10 -3 kg/to.
  • this dosage total porosity remains substantially unchanged and within this value the ratio of the gravitation pores decrease by 11 % and that of capillary pores increase by 28 % which positively effects both water and nutrient delivery.
  • composition A applied in the form of a solution percolates through the gravitation pores towards the deeper inner layers. By infiltrating into the layer it forms a superficial layer on the soil particles and thus decreases the diameter of the pores. Hence, a part of the pores begin to show a capillary behaviour and become capable of storing the taken-up water. Due to its high viscosity the composition fills up a part of the gravitation pores and consequently impedes the downward movement of humidity.
  • composition A When adding composition A to a soil without any structure it plasters the parts of the frame together and brings about a structure being watertight to a certain extent, crumby and more easily cultivable.
  • the increase of crumbwater-resistance exhibits a favourable effect on impermeable soils, wherein the swelling of clay minerals is decreased by superficial film-formation and consequently temporary improvement of the agronomical structure can be observed.

  • composition A is used in order to decrease the nutrient losses of the soil.
  • a 60 cm. high sand column is filled into a plastic tube and the amount of nutrient elements washed out with 150 mm. of precipitation is determined after treatment with doses of 1.4-4.3-13.0 x 10 -3 kg/to.
  • the best results related to the control are obtained by using a dose of 4.3 x 10 -3 kg/to.
  • the amount of washed-out K 2 O is 65 % of that of the control.

  • the process of the present invention is suitable for the speeding up of the initial growth of plants sown in spring.
  • Example 5 Composition A is added to increase the floatability and sticking of pesticides
  • the polymer increases the viscosity of the aqueous solutions while on the other it behaves as a microencapsulating substance and hence increases the floatability and duration of action of pesticides.
  • floatability is measured by using the following commercially available pesticides : Buvinol 50 WP, Thiovit S and Adol 80 WP. The results are summarized in Table 5.
  • composition A increases the floatability of pesticides by about 5 % (the pesticides used as test substance show good floatability per se) .
  • composition A enhances the sticking of the pesticide onto the leaves of plants as well.
  • the composition of the present invention can be particularly advantageously used in the case of suspension fertilizers which are prepared on the spot of application and used within 12-24 hours after preparation.
  • Example 7 In order to decrease vegetable evaporation composition A is applied at the transplantation of vegetable and tobacco seedlings and onto the stock (stand) by dipping or spraying on the leaves. Thus the stress of the seedlings due to water famine can be decreased. The spray continuously covers the surface of the leaves and thus the stress of seedlings due to water famine and transpiration can be reduced. The results are summarized in Table 8.
  • composition B The effect of composition B on the losses of water and on the withering of seedlings occuring on transplantation is determined.
  • Seed dressing test is carried out by using various formulations of fungicidal seed dressing agents prepared from the aqueous solution of composition B according to Example 2.
  • Dicotyledonous weeds Chenopodium album (1) , Amaranthus retroflexus (2) , Sinapis arvensis (3) , Raphanis raphanistrum (4) and Datura stramonium (5) pre-cultivated in a glass-house are subjected to the treatments specified in Table 11 in pots filled with horticultural peat ; 5 plants are sown in each pot.
