YaraVita® SAFE K™

Image of YaraVita® SAFE K™
YaraVita SAFE K is a highly concentrated liquid potassium product designed for foliar application. YaraVita Safe K is quick acting and mobile within the plant, making it ideal for situations where soil application is not possible or practical to overcome problems of availability in the soil. YaraVita Safe K does not contain chloride or nitrate so is suitable for use on a very wide range of crops whatever the situation.

The liquid formulation makes it easy to measure, pour and mix the product in the spray tank.

The product is specifically formulated to provide maximum crop safety. This helps to ensure that application will not cause damage to the crop which can reduce it's market value.

A broad tankmixability makes it easy to co-apply the products with agrochemicals, saving both time and money. Just as important, free access to Tankmix information online or via smart phones makes it quick and easy to check whether products can be co-applied.

Apples

Apple: 5 l/ha at bud burst. Also, two to three applications of 2 to 3 l/ha at 10 to 14 day intervals starting at petal fall. Water rate: 500 l/ha. Pommiers: 5 l/ha au stade débourrement. Aussi, deux ou trois applications de 2 à 3 l/ha à 10-14 jours d'intervalle en commençant dès le début de la chute des pétales. Volume d'eau: 500 l/ha.
Barley

Barley: 5 l/ha from early tillering to 2nd node detectable (Zadoks G.S. 21 to 32). Repeat at 10 to 14 day intervals between these growth stages as necessary. From 2nd node detectable onwards apply 5 l/ha, if necessary, up to the end of inflorescence (Zadoks G.S. 32 to 59). Water rate: 50 to 200 l/ha. For aerial application: 3 l/ha from early tillering to 2nd node detectable (Zadoks G.S. 21 to 32). Repeat at 10 to 14 day intervals between these growth stages as necessary. Water rate: 20 to 50 l/ha.
Beans

Beans: 5 l/ha before flowering. Water rate: 30 to 200 l/ha. Haricots: 5 l/ha avant floraison. Volume d'eau: 30 à 200 l/ha.

Fertigated Crops

Fertigation: All crops: Use at a dilution of 0.05% v/v (0.5 litres per 1000 litres of water). This will produce a solution containing 250 mg/l potash. Alternatively: 45 to 65 l/ha (or 325 to 700 ml / cubic metre of water). Alternatively: Use at 2 to 3 litres per 1000 metres squared. Repeat at 7 to 14 day intervals as necessary.

Wine Grape

Grapevines: 3 to 5 l/ha as soon as there is sufficient new season leaf growth to intercept a spray with up to two repeat applications at 10 to 14 day intervals prior to flowering and/or 3 to 5 l/ha at fruit set, pea-sized berries, first colour softening/one month before harvest. Water rate : 200 to 500 l/ha. Vignes: 3 à 5 l/ha dès que possible sur les nouvelles feuilles en début de saison avec applications répétées à 10 à 14 jours d'intervalle jusqu'au début floraison, et/ou 3 à 5 l/ha aux stades nouaison, fermeture de la grappe et début véraison/un mois avant vendange. Volume d'eau: 200 à 500 l/ha.

Corn

Maize: 5 l/ha at the 4 to 8 leaf stage. Water rate: 30 to 200 l/ha. Maïs: 5 l/ha au stade 4 à 8 feuilles. Volume d'eau: 30 à 200 l/ha.
Oats

Oats: 5 l/ha from early tillering to 2nd node detectable (Zadoks G.S. 21 to 32). Repeat at 10 to 14 day intervals between these growth stages as necessary. From 2nd node detectable onwards apply 5 l/ha, if necessary, up to the end of inflorescence (Zadoks G.S. 32 to 59). Water rate: 50 to 200 l/ha. For aerial application: 3 l/ha from early tillering to 2nd node detectable (Zadoks G.S. 21 to 32). Repeat at 10 to 14 day intervals between these growth stages as necessary. Water rate: 20 to 50 l/ha.

Canola

Oilseed rape / canola: 5 l/ha at the 4 to 6 leaf stage. Repeat as required for moderate to severe deficiency at 7 to 14 day intervals. Water rate: 50 to 200 l/ha. Colza: 5 l/ha au stade 4 à 6 feuilles. Répéter si nécessaire en cas de carence moyenne ou severe à 7 à 14 jours d'intervalle. Volume d'eau: 50 à 200 l/ha
Peas

Peas: 5 l/ha before flowering. Water rate: 30 to 200 l/ha. Pois: 5 l/ha avant floraison. Volume d'eau: 30 à 200 l/ha.

Potatoes

Potatoes: One application of 10 l/ha or two applications of 5 l/ha during tuber bulking (as soon as first-formed tubers are 10 mm in diameter). Allow 10 to 14 days between applications. Also, 5 l/ha following petiole analysis, during tuber bulking. Water rate: 200 l/ha. Pomme de terre: une application de 10 l/ha appliqués ou 2 applications de 5 l/ha à 10-14 jours d'intervalle pendant le grossissement des tubercules (dès que les premiers tubercules ont atteint 10 mm de diamètre). Aussi, les applications de 5 l/ha à 10-14 jours d'intervalle pendant le grossissement des tubercules peuvent être répétées si nécessaire (selon analyse pétiolaire, etc...). Volume d'eau: 200 l/ha.
