Plum tree

Application technology:

1. Pre-treatment of seedlings. Lignohumate solution concentration – 0.05% (5.0 g of Lignohumate A, AM, or 0.025 l of Lignohumate B, BM per 10 l of water). Planting stock treatment (soaking for up to 10-20 hours) by a Lignohumate solution with consumption rate of 1 l per 5 seedlings.

2. Watering of seedlings at the sprouter, during planting and after planting. The preparation is applied at the seedling phase while still in a nursery garden and also at the moment of planting them into the open ground: to be added into water or into fertilizer solutions. Lignohumate solution concentration – 0.02% or 20 g of Lignohumate A, AM, or 0.1 l of Lignohumate B, BM per 100 l of watering solution.

3. Foliar dressing at early bud opening. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare at a consumption rate of 200-300 l/hectare and 900 g of Lignohumate A, AM, or 4.5 l of Lignohumate B, BM per 1 hectare at a consumption rate of 800-1200 l/hectare. Standard or low-capacity sprayers can be used.

4. Foliar dressing at early fructification. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare at a consumption rate of 200-300 l/hectare and 900 g of Lignohumate A, AM, or 4.5 l of Lignohumate B, BM per 1 hectare at a consumption rate of 800-1200 l/hectare. Standard or low-capacity sprayers can be used.

5. Foliar dressing at the fruit growth phase. Application rate of the preparation – 150 g of Lignohumate A, AM, or 0.75 l of Lignohumate B, BM per 1 hectare at a consumption rate of 200-300 l/hectare and 900 g of Lignohumate A, AM, or 4.5 l of Lignohumate B, BM per 1 hectare at a consumption rate of 800-1200 l/hectare. Standard or low-capacity sprayers can be used.

It is recommended to apply Lignohumate in a mixture with protectors and soluble fertilizers.

6. 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;

- better merchantability of the crop (increased evenness/intensity of colouring of fruits);

- increased crop yield;

- better crop quality (higher content of sugar and at the same time lower percentage of acids in fruits).

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