Fertigation: Combining fertilizer with irrigation

Fertilizer Storage Tank
This weekend we were fertigating. Fertilization and irrigation are combined to form a process called fertigation using the irrigation system. Nitrogen fertilizers are used in the spring and early summer to promote almond and vegetation growth. Since almonds are high in protein they use a lot of nitrogen to form proteins in the almonds. We also fertigate with potassium, almonds are high in potassium therefore the tree takes up a lot of potassium out of the ground to produce the crop. This potassium needs to be replaced in the soil for next years crop to be successful.

The process of fertilizing is made easier for farmers who use drip or micro irrigation. Fertilizer is delivered to our storage tanks by the semi truck load. Next, when the timing is right for the tree to efficiently use the fertilizer we pump the fertilizer into the irrigation system. Since we use drip irrigation on our farm, we simply pump the fertilizer into the irrigation system. Then the water drips from the hoses in the field and fertilizer is delivered directly to the tree.

Before we installed drip irrigation we used to drive tractors with a trailer and tank spreader through the orchard. This required more man power, more time and extra costs to operate another piece of equipment. This also wasted fertilizer due to evaporation because the fertilizer wasn't being applied immediately with irrigation. With fertigation we are more efficient and smart with our farming practices; we use less inputs, we are easier on the environment and the bottom line is much happier.

Until Next Time,

Almond varieties

Did you know there are over 30 different varieties of almonds grown commercially?! All have their own unique purpose, size, and shape. Most almond farmers, have multiple varieties in the same orchard, the most popular being nonpareil. Nonpareil is the prettiest almond, most widely produced and comes with the biggest return back to the grower. But we can't all farm nonpareils, they need to be pollinated somehow. Almonds typically need at least two varieties in an orchard because the almond flower cannot pollinate itself like other fruit trees can. We learned about that with the almond bloom and bee blog!! So we have pollinator varieties that complement other varieties and offer their own unique purpose. I am going to outline a few of the more widely grown varieties for you, but feel free to check out The Almond Board of California's full guide.


Nonpareil has the most uses and purposes of any other nut. It can be used in raw form, blanched, processed or anything you …

Almond by-products

When people think of almond uses they tend to just think of using the almond meat. Almonds have multiple by-products actually. When almonds are processed at the huller the almond meat is separated from the hull and shell. The hulls, shells and hash are also sold and used.

Almond hulls are the green out most layer of the almond while on the tree. The hull is what splits and starts the countdown to harvest. Once the almond has dried in the field, the hull also dries and begins to separate from the almond. At the huller, they remove the hulls and stock pile them until sold. Almond hulls are sold for animal feed, most commonly dairy feed. The hulls actually add nutrition to the animals diet and aid in healthy milk production. Growing up on my family's farm, we used the hulls to feed our breeding sheep. It was cheaper than grain, helped to add nutrition to the animal diet and while filled them up faster.

Almond shells are the hard layer between the hull and the almond meat. …

What fertilizers do almonds need?

It's spring and the almond trees are covered with shiny leaves and growing nuts. The trees are beautiful and full of new life. As they grow the 2016 harvest crop, they need fertilizer to help them grow. Fertilizer is like plant food or vitamins that give the trees a little extra boost. Just like you feed your garden fertilizer, your rose bushes plant food, or like how you take your daily vitamins, we feed our almond trees fertilizer.
We prefer the fertigation method to fertilize our trees through the water in our irrigation drip hoses. This helps us to be more efficient and effective in our fertilizer use. When we fertilize in the spring we use three different kinds of fertilizers; Nitrogen, Potassium and Zinc. It is like a farmers version of a a perfect vitamin combination.

Nitrogen is important to help encourage leaf growth and nut development. Nitrogen provides the building block to form protein and oils.  One of the key reasons you probably eat almonds is because they are high …
