BLACKJAK

Biostimulant as a suspension concentrate (SC) to enhance efficiency and improve nutrient uptake by supporting the plant during abiotic stress moments

Improves NUE, EUE and WUE
Chelating effect
Used as pH balancer of the soil
Improved plant photosynthesis
Unblocks nutrients for improved uptake by the plant
Improves soil structure

BLACKJAK® is a concentrated aqueous suspension of Leonardite, rich in humic, fulvic, and ulmic acids and contains a high organic matter content. Applicable as a soil conditioner (applied to the entire field and/or via drip irrigation) and as a foliar spray. Its naturally acidic pH (3 to 5) allows growers to mix with acidic fertilizers and can be used to lower pH in alkaline solutions. As a soil or foliar application, it promotes nutrient uptake and improves photosynthetic efficiency. Humic acids are natural chelators. Soil applications of BLACKJAK® help release blocked macro- and micro-elements for plant uptake. When used on heavy clay soils, BLACKJAK® helps break clay bonds, improving soil structure, microbial activity, air and water circulation, and retention. BLACKJAK® is 100% natural Leonardite obtained exclusively as a by-product of mining activities

Environmental protection

OTHER APPLICATIONS: In combination with iron chelates (EDDHA 6% iron): 250 ml BLACKJAK® + 125 g EDDHA 6% iron per 1000 m2 (applied via pot irrigation) normally results in faster chelate uptake and faster correction of iron chlorosis. Applied via drip irrigation: Vegetables: immediately after planting and then every 3-4 weeks at 300-500 ml/1000 m2. Field crops (corn, cereals, etc.): 2.5 l/ha, repeated 5-6 times during the growing season. Mixed with foliar fertilizers: BLACKJAK® 50 ml / 100 L water. As a buffer in the spray tank to lower pH: BLACKJAK® 50 ml / 100 L water. Mixing: Fill the spray tank halfway with water. Add BLACKJAK® in the recommended amount, optionally with foliar fertilizers and desired crop protection products. Add the remaining amount of water during mixing, and the mixture is ready for spraying.
