Potato

Application technology:

1. Pre-treatment of bulbs. Application rate of the preparation – 500 g of Lignohumate A, AM, or 2.5 l of Lignohumate B, BM per 1 ton of bulbs. Bulb pre-treatment with consumption rate of 100 l per 1 ton of bulbs. Combination with protectants or bio-preparations is recommended. Machines used – standard installations for pre-treatment of bulbs or hand-operated sprayers.

2. Foliar dressing when plants reach 8 to 12 cm in height. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare. Consumption rate of the solution – 200 - 300 l per one hectare. Standard or low-capacity sprayers can be used.

3. Foliar dressing at the budding phase. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare. Consumption rate of the solution – 200 - 300 l per one hectare. Standard or low-capacity sprayers can be used.

4. Foliar dressing at the after bloom phase. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare. Consumption rate of the solution – 200 - 300 l per one hectare. Standard or low-capacity sprayers can be used. It is recommended to apply Lignohumate in a mixture with protectors and soluble fertilizers.

5. If an irrigation system is used, then the preparation is to be applied with water several times per season. Lignohumate solution concentration – 0.01% or 10 g of Lignohumate A, AM, or 0.05 l of Lignohumate B, BM per 100 l of watering solution. If drip irrigation is used, then the preparation is to be applied at the last or last-but-one watering 1 time each 7-10 days. Lignohumate solution concentration – 0.01% or 10 g of Lignohumate A, AM, or 0.05 l of Lignohumate B, BM per 100 l of watering solution.

Thus, thanks to the above described properties we have:

- increased drought tolerance;

- increased crop yield;

- better merchantability of the crop (better evenness of bulbs);

- crop quality improvement (increased bulb starchiness, lower content of nitrates and heavy metal salts).

By virtue of its physiological requirements it is most preferable to apply to Potato a potassium form with addition of a set of microelements.
