Usage overview for almonds: Urea and Potash

To assess the nutrient status of our orchard, we take leaf samples and have them analyzed.

Typically, Nitrogen is the only major nutrient that needs to be added regularly in almond orchards. Latest research indicates that applying smaller amounts of nitrogen several times during the growing season is greatly beneficial than applying one big dose.

1. Nitrogen: Nitrogen is an essential nutrient for the production of proteins, nucleic acids(DNA) and amino acids, and almond trees require an adequate annual supply for proper growth and productivity.

UN-32 (Urea Ammonium Nitrate with 32% nitrogen) is applied through the irrigation system at 220 pounds of N per acre and is split into equal applications in April, May and July.

2. Potassium: Potassium sulfate aka "potash" at 500 pounds per acre is banded along the tree row in late fall. Please note that we take away large amounts of K in the form of almonds so we have to replenish it from time to time.

Urea pellets (we don't use pellets; we apply a liquid form it via irrigation system which is more efficient):

Orchard removal logistics..

Orchard removal includes felling trees, grinding, stump removal and transportation plus land leveling.

So they put trees into a big chipper or grinder and shredding the wood into small pieces. Any wire in the trees is removed by magnets and a dirt separator is used so they end up with a clean product that is hauled off to a site where it is burned to produce electricity. The old method of pushing the trees into huge burn piles has been phased out by the Air Resources Board.

We see the Natural Resources Conservation Service (NRCS) has a cost sharing program (EQIP, Environmental Quality Incentives Program) to encourage people to chip rather than burn. For orchard removal they will pay up to $75 per acre.

Fortunately for us, Lane served on the board of directors of the local resource conservation district for 10 years so he has contacts at NRCS and can find out more details. The following link is a two-page description of the program.
