Cucumber
One of the most popular crops in vegetable growing, it’s grown both in open ground and in greenhouses, hydroponic and aeroponic farms. Cucumber is respected not so much for its nutritional value, but for the freshness and taste of the fruit, for the combination with other products, abundance of varieties and the diversity of preservation methods.
Peculiarities
It is better not to sow cucumbers after other pumpkin and after nightshades such as beets, tomatoes or potatoes. The most favorable predecessors are considered winter cereals and legumes, fodder crops, cabbage, carrot and onion. High-stemmed corn, sunflower, sorghum or soybeans are sown on windy sides to protect cucumber seedlings.
Cucumbers in open ground require soil preparation in advance. SatoSoil® improvers with SatoHum® watering, or, if necessary, with liquid Sato® Turbo NPK organo-mineral fertilizers are added at pre-sowing.
Soil conditioning increases friability and preserves the fertile soil layer, and biostimulants let uptake minerals even before sowing.
Pre-sowing seed treatment includes warming or alternating hardening by holding at different temperatures and dressing with SatoHum® K to obtain coordinated seedlings. The compound also proved to be excellent when germinating seedlings in greenhouses. For hydroponics we’ve developed specific formulation Sato® Turbo 3-1,5-6.
At the beginning of the growing cycle, to stimulate abundant flowering, sprouts should receive potassium and nitrogen, so Sato® Turbo NPK, organo-mineral fertilizers are used, which gradually release minerals and promote the best absorption of nutrients due to elevated content of humic and fulvic acids. While vegetative green mass and lashes grow, the cucumber consumes more nitrogen, and then potassium uptake is key for optimal fruiting.
To increase the stress resistance of crops in open ground and in greenhouses during pest attacks, to combat aphids, spider mites, fungal diseases, as well as to prevent diseases, liquid growth regulators SatoHum® are applied, strengthening the vegetative organs of the cucumber and avoiding sprout lodging. SatoHum® K is an effective protection in critical phenodates for cucumber: in the stages of the ovary and fruit filling.
To correct some deficiencies in cucumbers our Sato® Turbo with micronutrients (boron, copper, molybdenum, manganese, and zink) are recommended.
Signs of nutrient deficiency in cucumber and fruits defects
- yellowing and shrinkage of the leaves - lack of nitrogen;
- thick shortened stems, excessive green mass gain, many tendrils, few flowers - excess nitrogen;
- lightening or browning of leaves edges, shrinkage of fruits - potassium starvation;
- brown spotting, dark green leaves - phosphorus deficiency;
- yellow-brown old leaves, signs of burns of the root system - excess potassium;
- leaf chlorosis, insufficient photosynthesis - magnesium deficiency;
- whitening of foliage, rapid withering of green mass, drying and falling of flowers, non-ripening and deformation of the fruit - boron deficiency;
- sluggish shoots, falling of flowers, small and deformed fruits, lax skin - lack of calcium and possibly copper;
- on alkaline grounds is common an excess of magnesium and a deficiency of iron.

WARNING AND GENERAL RECOMMENDATIONS: 4 Sato® Steps is a comprehensive crop care system that provides the basic crop needs for the main 12 macro, meso and micronutrients for an optimal growing cycle and unlocking the potential of each crop.
SOILS: In pre-sowing application of SatoSoil® improvers, the minimum rate is introduced; when autumn applying, the maximum rate is recommended. When applying Sato® Turbo organo-mineral fertilizers after SatoSoil® improvers, the minimum rate is applied; if the soil hasn’t been treated, the maximum rate is applied. For irrigation, it’s recommended to activate granulates (soil improvers) with SatoHum® K liquid formulation or Sato® Turbo NPK liquid organo-mineral product.
SEEDS/SEEDLINGS/VEGETATION BEGINNING: Treatment of seeds and seedlings with SatoHum® K formulation is compatible with treatment by classical protectants without reducing the rates of their application, and helps to increase the viability of seedlings, the development of the plant and its fruitfulness.
GROWTH: Our SatoHum® solutions have a guaranteed composition with high content of humic and fulvic acids with amino acids of plant origin. It is not recommended to exceed the total applying dose of SatoHum® liquid formulations over 6 l/ha/season, starting from the germination/seedlings phase. If SatoHum® K is used for prophylactic purposes, it is recommended to apply the minimum dose.
HARVEST: Simultaneous fertilization with several SatoHum® products is not expected, excepting the soil improver’s activation. It’s not recommended to exceed the specified application rates. For single, not systemic application of SatoHum® products, the maximum dosage of the product is recommended.
