BRT Ag & Turf 21-1-0 is produced by combining 3 separate nitrogen, phosphate, bio-Lith and humic acids. 21-1-0 can be used on most field crops, vegetables, fruit and nut trees and more. Since it contains 100% orthophosphate, which is immediately available to your growing crop, 21-1-0. BRT Ag & Turf 21-1-0 has a pH of 7, making it as safe as water and effective as a foliar spray. 21-1-0 can also be applied through drip irrigation systems. To insure best performance, use 21-1-0 when there is adequate humidity, moderate temperatures and adequate soil moisture. Foliar sprays should be made during the early morning and late evening hours.
MIXING INSTRUCTIONS
Brt Ag & Turf’ 21-1-0 mixes completely in water with minimal agitation.
- Fill tank roughly ½ full of water and begin agitation.
- Add 21-1-0 to mix tank
- Add other pesticides and/or nutrients (be sure to check compatibility prior to mixing)
ATTENTION: Always check compatibility with other products prior to use. 21-1-0 Foliar is not compatible with products containing calcium.
SOIL APPLICATION RATES
Vegetables: For sprinkler irrigated fields, spray or dribble directly over the seed at planting. For furrow irrigated fields, 21-1-0 may be diluted with water if desired.
Corn, Cotton, Melons: Inject ½-2” to the side of the seed furrow. Use 3-10 gallons/acre. 21-1-0 may be diluted with water if desired.
Vegetable, Field Crops, Fruits, Fruit and Nut Trees: Apply 1-3 gallons of 21-1-0 in at least 5 gallons of water/acre. Multiple applications may be useful. Use of Contact (nonionic spreader/sticker) may enhance coverage and increase plant uptake. Do not apply more than 3 times per growing season. Apply when the crop is under severe stress. For best results, use the lowest possible volume that will ensure complete coverage and small droplet size.
Drip Irrigation (All Crops): Use 3-10 gallons of 21-1-0 per irrigation. Continue irrigation for at least 2 hours to insure adequate fertilizer coverage.
