Strengthen Plants from the Inside Out

KIR is a premium liquid biostimulant formulated with stabilized ortho-silicic acid, chitosan, and essential micronutrients — engineered to enhance plant resilience, boost photosynthetic efficiency, and maximize crop yield and quality.

Key Benefits

  • Stress Mitigation — Reduces the adverse effects of abiotic stress including drought, salinity, and heat
  • Yield & Quality — Increases crop yield and improves fruit and vegetable quality at harvest
  • Antioxidant Activation — Chitosan activates antioxidant enzymes, protecting plants from oxidative damage
  • Photosynthesis Support — Encourages the build-up of bioactive compounds and bolsters photosynthetic activity
  • Extended Shelf Life — Pre-harvest application helps extend post-harvest shelf life of fruits and vegetables

Guaranteed Analysis

  • Silicon (Si): 0.4%
  • Chitosan: 7.7%

Applications

KIR is suited for a wide range of growing systems and application methods:

  • Fertigation — Apply through drip or irrigation systems throughout the growth season
  • Foliar Spray — Apply directly to foliage for rapid uptake and stress response
  • Hydroponic Systems — Compatible with recirculating and run-to-waste systems
  • Seed & Plug Treatment — Protects seeds and enhances germination rates
  • Pre-Harvest — Apply to fruits and vegetables before harvest to extend shelf life

KIR is compatible with most fertilizers, biostimulants, and crop protection products. A small-scale compatibility test is recommended before broad application.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.

Comparable to high end mens shops!
Fit Type: Regular Fit, Color: Blue, Size: Large
Beautiful, heavy blue Oxford comparable to upper end mens store at 75% less! Full cut, great for casual wear or sending out for professional starching. Downside, no pocket, but I had mine monogramed wear the pocket would be and it looks like an expensive dress shirt. I bought more (with pockets) in blue & white

Heavier fabric, very durable
Fit Type: Regular Fit, Color: Grey, Size: Large
3 stars. Pretty nice shirt but the fabric is a bit firmer than i like. I iron it when i usually wear it so that it looks half decent since wrinkle resistance is low or poor. I usually have to use a higher setting on the fabric since the material is thick making it alot heavier. Overall great for the lower end cost, anything that beats it would probably be double the price. I work in a cubicle so this works well for me, a simple shirt, with a simple color.
