Crop Benefits

  • Fast spring or fall forage with excellent grazing potential: oats establish quickly and can provide strong early pasture/forage growth.

​​​​​

  • Legume-powered nitrogen: forage peas help supply nitrogen through biological fixation, supporting both forage and soil fertility goals.

​​

  • Nutrient capture & recycling: oats and brassicas help scavenge excess nitrogen and hold nutrients that might otherwise be lost—then release nutrients back as residue breaks down.

​​

  • “Biological tillage” for soil structure: radish’s deep taproot and turnip’s root system help reduce compaction, improve pore space, and support better root exploration for the next crop.

​​

  • Improved water infiltration & oxygen movement: taproot channels created by radish are associated with better water infiltration and air exchange in tighter soils.

​​

  • Adds biomass/organic matter: oats build dependable above‑ground biomass; brassicas break down relatively quickly to feed soil biology and nutrient cycling.

​​

  • Weed suppression: oats provide quick, competitive cover; brassicas (turnip/radish) can contribute natural weed‑suppressive effects (glucosinolates).

​​

  • Erosion protection (“soil armor”): oats create rapid ground cover and a fibrous root system that helps hold soil during vulnerable windows.

 

  • Supports soil biology: oats have been noted to increase beneficial mycorrhizal fungi; radishes can attract earthworms—both positives for soil function.

​​

  • Simple management in many areas: oats often winterkill in colder zones, helping simplify spring termination while leaving residue.

​​

  • Highly nutritious and palatable for cattle: GrazMaxx provides a balanced forage mix of grasses, legumes, and brassicas. Oats and forage peas deliver excellent energy and protein, while turnips and radish add highly digestible, high‑quality forage—especially after light frost.

​​

  • Excellent digestibility: Brassicas (turnips and radish) are very digestible and energy‑dense, helping support weight gain when managed correctly.

​​

  • Well‑suited for rotational or strip grazing: Grazing management helps maintain forage quality and supports even utilization of tops and roots.

​​

  • Works for multiple livestock species:

✅ Cattle – Excellent fit; primary target species

✅ Sheep & goats – Highly palatable and nutritious; well‑suited for small ruminants

​​

  • Fiber balance matters: While brassicas are highly nutritious, they are lower in fiber. The oat component helps balance the ration, and providing access to dry roughage (hay or pasture) is recommended when grazing any brassica‑based mix.

​​

  • Gradual introduction recommended: Introduce livestock slowly to allow rumen adaptation and avoid digestive upset—standard practice with high‑quality cover crop forages.
