Section 1
Crop Status & Growing Season
|
|
July turns up the heat, triple-digit afternoons, peak irrigation demand, and crops racing toward harvest. Almonds are in hull split, wheat harvest is wrapping up, cotton is in bloom, and table grapes are moving. Irrigation management and mite, worm, and lygus pressure define the month. With commercial nitrogen still expensive, summer is the smart window to stockpile compost and book fall soil and water testing.
| 🍐 Almonds |
Hull Split Active |
|
|
Hull split is underway on early varieties. Navel orangeworm hull-split sprays are the top call this month, time them to moth flights and egg-laying. Mite pressure peaks in the heat, scout twice weekly. Manage irrigation to finish kernel fill without triggering hull rot. First crackouts and early harvest approach late month.
|
|
| 🌿 Pistachios |
Nut Fill / Shell Hardening |
|
|
Shells hardening; kernel fill ramping into late July. Maintain steady irrigation and potassium. Navel orangeworm and carpophilus beetle monitoring is critical, keep traps current. Watch Botryosphaeria and Alternaria late blight in the heat. Strong on-year crop, protect it.
|
|
| 🪓 Walnuts |
Nut Sizing / Kernel Fill |
|
|
Nuts sizing; kernel fill beginning. Codling moth 2nd flight is the key spray window, stay on the degree-day model. Walnut husk fly traps should be up and monitored. Keep water consistent, heat and moisture stress now cut kernel quality and size. Watch mites and aphids.
|
|
| 🍇 Wine & Table Grapes |
Veraison / Harvest |
|
|
Coachella and early SJV table grapes are harvesting; wine grapes near veraison. Protect clusters from sunburn during heat spikes. Ease late-season nitrogen and shift to potassium to size and finish. Continue mildew vigilance until veraison. Time irrigation to sugar and quality targets.
|
|
|
|
|
Fruit sizing through summer. Heavy, consistent irrigation is critical, kiwis are shallow-rooted and heat-sensitive. Manage canopy for light and airflow while shading fruit from sunburn. Maintain potassium for sizing. Watch for mites and leafroller in the heat.
|
|
|
|
|
Fruit sizing through summer, consistent water prevents splitting and drop. Keep potassium up. Citrus thrips and red scale pressure continues; Asian Citrus Psyllid monitoring remains a top priority, report symptoms to CDFA. Guard young trees against heat stress.
|
|
| 🌿 Cotton |
Bloom / Peak Water |
|
|
Cotton is squaring into bloom, peak water and nutrient demand is here. Keep irrigation ahead of the crop through peak bloom. Lygus is the #1 threat now, sweep fields and treat on threshold. Watch aphids and spider mites in the heat. Protect fruit retention for yield.
|
|
| 🌽 Corn (Silage & Grain) |
Tassel / Grain Fill |
|
|
Early silage corn is tasseling into grain fill; later plantings stacking leaves. Peak water demand, do not let corn stress at tassel/silk. Fertigate remaining N through tassel. Watch spider mites, corn borer, and worms. Silage demand from dairies remains firm.
|
|
| 🌾 Wheat (Winter) |
Harvest Complete |
|
|
Winter wheat harvest is wrapping up across the Valley. Now is the time to pull post-harvest soil samples and plan fall rotations. Consider a summer compost application on fallow ground to rebuild organic matter and biology ahead of next season, the most cost-effective window of the year.
|
|
|
| 🧪 |
Section 2
July Fertilizer Requirements
|
|
July fertility is about finishing crops through peak heat without wasting inputs. Tree crops shift toward potassium for fill and finish while nitrogen tapers; cotton and corn hit peak demand. Fertigation timing matters most, heat sharply cuts uptake efficiency. With nitrogen prices high, compost applied this summer builds organic matter and unlocks nutrients already in your soil, stretching every fertilizer dollar.
| Crop |
Primary Nutrients |
Micros / Notes |
Timing & Method |
| Almonds |
N largely complete, taper to avoid hull rot. Potassium is the priority through kernel fill and hull split. |
Plan post-harvest Zn & B foliar for next year's buds. HIGH Compost builds season-long N mineralization. |
Fertigate K through hull split. Ease water at split to limit hull rot, then finish. |
| Pistachios |
Continue K for nut fill and shell. Moderate N, 20–30 lbs/ac only if tissue supports. |
B for shell integrity. HIGH Maintain zinc program. |
Fertigation 1–2×/week. Keep water steady through fill. |
| Walnuts |
K critical for kernel fill. Final N split only if tissue indicates, avoid excess. |
Zn & Mn foliar if needed. MED Watch late-season deficiency. |
Fertigation via micro-sprinklers. Tissue test to confirm rates. |
| Grapes |
Ease N post-set. Potassium drives sizing and sugar, deliver via fertigation. |
Mg foliar if interveinal yellowing. MED Hold heavy inputs near harvest. |
Fertigation to quality targets. Stop N well ahead of harvest. |
| Kiwis |
Potassium for fruit sizing. Moderate N, avoid soft growth in the heat. |
Ca & Mg if tissue low. MED Keep micros balanced. |
Fertigation every 10–14 days. Steady water is non-negotiable. |
| Citrus |
N: 20–25 lbs/ac. K for fruit sizing and split prevention. |
Zn & Mn foliar. MED Iron chelate if chlorotic. |
Fertigation every 7–14 days. Pair with steady summer irrigation. |
| Cotton |
Peak bloom demand. N to support fruit set; K for boll fill: 40–60 lbs/ac split. |
Foliar K on heavy loads. HIGH Boron supports retention. |
Side-dress/fertigate through peak bloom. Match N to plant map. |
| Corn |
Finish N through tassel via fertigation. K per soil test for grain/silage fill. |
S on sandy/low-OM soils. HIGH Zn if deficient. Compost builds long-term OM & N. |
Fertigation through tassel/silk. Do not stress at pollination. |
| Wheat |
Harvested, no in-season fertility. Plan the next crop from a fresh soil test. |
Pull post-harvest soil samples. LOW Consider summer compost on stubble. |
Soil test now; apply compost to fallow ground to rebuild OM. |
|
Advisor Note: July heat can cut fertigation uptake efficiency by 30–50%, run events in the early morning or late evening and keep water steady. Nitrogen is expensive this season; compost applied this summer supplies organic nitrogen, feeds soil biology, and unlocks nutrients already present but unavailable. Pair a mid-summer soil and tissue test with your program to target inputs and protect budget.

Section 4
Product Spotlight
|
|
With summer here and commercial nitrogen still expensive, this month we’re spotlighting two cost-cutting fundamentals: Compost, dairy manure and green waste, as a nitrogen and organic-matter alternative, and Soil & Water Testing to build a targeted, budget-conscious nutrition program. Both are about doing more with less: feeding your soil biology and spending only where the data says it pays.

Compost is the workhorse of every soil-health program. Dairy and green-waste compost replace a meaningful share of commercial nitrogen while rebuilding organic matter, the fuel for healthy soil biology. That biology unlocks nutrients already present in your soil but not plant-available, so you get more from what you already own.
|
| ✓ Nitrogen alternative when commercial N is expensive |
| ✓ Builds organic matter & feeds soil microbial life |
| ✓ Unlocks tied-up nutrients already present in your soil |
| ✓ Improves water-holding capacity & soil structure |
| ✓ Summer is the cheapest window, stockpile while yard inventories are highest |

Summer Strategy: Compost yards carry their highest inventories in summer, which is when pricing is most competitive, stockpiling now locks in savings ahead of fall and dormant-season application. Nitrogen is expensive this year; compost offsets part of that cost while improving soil health. Pair it with a soil and water test so every dollar, compost or commercial, is placed where your data shows the return. Ask us to build your program.

This Month in American History
July 4, 1776, Independence Day: 250 Years of American Freedom
|
On July 4, 1776, in Philadelphia, the Second Continental Congress adopted the Declaration of Independence, announcing to the world that thirteen colonies would stand as free and independent states. Thomas Jefferson’s words, that all are endowed with the unalienable rights of life, liberty, and the pursuit of happiness, became the founding promise of a new nation.
This year marks the 250th anniversary, America’s Semiquincentennial. From the farms and workshops of 1776 to the fields of the Central Valley today, that promise has been carried forward by ordinary people willing to work, build, and defend it. The signers pledged their lives, their fortunes, and their sacred honor, knowing the cost of failure was everything.
Two and a half centuries later, we still plant, grow, and harvest under the freedom they declared. Independence Day is a reminder that this nation was built by people who bet on themselves and on each other, and that the work of keeping it free belongs to every generation, including ours.
