Indiana NRCS - Pasture Condition Score Training

New Pasture Condition Score Sheet Overview
📌 The Pasture Condition Score (PCS) sheet involves a visual evaluation of ten indicators, each rated from 1 (poorest condition) to 5 (best condition).
📋 Key identification fields at the top include Pasture ID, livestock type, soil/ecological site description, and seasonal weather trends.
📊 The goal is to identify the extent of pasture challenges and determine their likely causes by evaluating each indicator separately before combining for an overall score.

Indicator 1: Percent Desirable Plants
🌱 Desirable species are those preferred and rarely consumed by the specific livestock type, based on dry weight for standardization.
⚖️ Invasive species usually fall into intermediate or undesirable categories, though preferences vary by animal (e.g., goats eat what cattle won't).
📊 Dry weight is crucial because moisture content can significantly alter the perceived weight of forage.

Indicator 2: Percent Legume
🌿 Benefits from legumes tend to plateau or flatten after reaching 40% legume content by dry weight.
⚠️ Legumes that cause bloating will result in a significantly lower score (e.g., over 40% bloating legumes score a 2).
📉 Visual estimation of legumes can be inaccurate; for instance, white clover may be only 50% of the wet visual estimate in dry weight terms.

Indicator 3: Plant Cover
☀️ This indicator assesses the live stem and green leaves, functioning as the pasture's "solar panel" for intercepting sunlight.
🌳 Factors influencing rating include grazing frequency, stocking rates, and the length of the rest period.
📱 The CanopyAU app can assist by measuring live green canopy, potentially providing a more accurate assessment than windshield viewing (e.g., showing 94.89% live green canopy).

Indicator 4: Plant Diversity
🤝 Diversity is essential for making a pasture a more reliable forage supplier across the growing season and improving resilience.
🌿 At least 15% is needed for any species group to be counted as a dominant species within one of the four main functional groups (cool season grasses, warm season grasses, legumes, non-grass forbs).
🏆 A field with four dominant desirable species and three functional groups present can still achieve a score of 5.

Indicator 5: Residue (Litter)
🛡️ Residue/litter primarily refers to material on the soil surface in various stages of decay, acting as protective cover for the soil.
💧 Adequate residue helps slow evaporation, keeps the soil cool, and improves rainwater infiltration.
🔍 To properly rate, one must pull back the canopy to assess the material directly on the soil surface, not standing dead material.

Indicator 6: Grazing Management
📉 Close and frequent grazing can cause loss of vigor, reduce desirable species density, decrease yield, and potentially promote erosion.
🧭 Zone grazing (heavy grazing at one end, light at the other, often near water/shade) can lead to a lower score (rating 3) even if the overall field is grazed to target heights.
📏 For fields under one acre, the risk assessment shifts to using 10% of the field area for the disturbed area, alongside distance to water criteria.

Indicator 7: Livestock Concentration Areas
💧 This assessment uses the size of the concentrated area (threshold of 0.1 acres, or $\approx 66 \times 66$ feet) and its proximity to water bodies.
⚠️ Areas less than 0.1 acres and less than 100 feet from water may receive a score of 1 due to high water quality risk.
✅ A field with no concentrated areas should receive the highest rating of 5 for this indicator.

Indicator 8 & 9: Soil Compaction and Soil Health Features
⛏️ Compaction issues should be assessed in the top 12 inches by digging two holes and comparing the ease of shovel penetration and root morphology.
🥕 Healthy roots should grow deep and downward, contrasting with horizontal growth which indicates compaction; soil structure should resemble cottage cheese, not plate-like layers.
🪱 Soil color and life (e.g., worm tunnels) are secondary indicators; the score is primarily dictated by the most adverse factor (roots/compaction).

Indicator 10: Plant Vigor
🟢 Plant vigor refers to plant health, primarily assessed by color and the rate of regrowth following a grazing event.
🟡 Yellowing plants suggest drought or insect damage, while pale green grass can indicate low fertility or poor growing conditions.
⭐ A pasture showing good recovery and healthy green color after grazing is likely to receive a score of 5.

Key Points & Insights
➡️ The STEP Point method is highly recommended as it provides data for at least five indicators, offering more confidence and reducing subjectivity.
➡️ Pastures should be rated at least annually to establish and track trends in condition scores, allowing management adjustments.
➡️ A low overall PCS rating signals one or more challenges, such as poor plant growth, weedy invasion, low forage quantity/quality, or soil loss.
➡️ When scoring soil health indicators, roots and compaction are primary, while soil color and life are used as secondary indicators.
