When properly managed, fertilizers help address the challenge of increasing production in an economically viable way while retaining the ecological integrity of cropping systems. However, if nutrients are not adequately available within a crop production system, fertility is mined from the soil, and the crop will never attain optimal yields. Conversely, if nutrients are supplied in excess or without managing risks, the possibility of nutrient movement away from the cropping system increases, potentially negatively affecting the environment.
A comprehensive non-phosphite foliar program in almond trial demonstrates significant yield increases three years in a row compared to the standard fertility program. Increased tree growth was also acheived.
Nut meat yield increased lbs, lbs and 1,lbs. The foliar materials were applied with an air blast sprayer at GPA.
Achieving consistency in set and minimizing alternate bearing cycles is the key to consistent high yields and larger profits. Following the Agro-K program ensures that trees have the right nutrients at the right time in the right forms and right mix.
We do not want the tree to lack for critical nutrients a key growth stages during the year. If that happens, yields suffer.

The trial has shown how almond tree vigor, overall health and increased nut meat production respond to a nutrient program based on these products: It is designed to increase the efficiency of ground-applied fertilizers by 1 promoting root growth and mass to maximize nutrient uptake, and 2 directly feed existing beneficial microbial populations such as Mychorrizae in the rhizosphere.
This increases native beneficial populations and their activity helping maximize nutrient availability from ground-applied fertilizers. This means applying the right nutrient, at the right time, in the right form, at the right rate, in the right mix.
As the season progresses, other foliar nutrient applications at key development timings like hull split will keep the tree on course for healthy growth and increased yield the following crop year. The process of a tree breaking dormancy is a very zinc-intensive process. Almond trees have a large early season demand for zinc to support leaf, root and vascular systems.
All these tissues require zinc to function and grow fully and properly.
Nut retention and nut size are dependent on large leaves with good chlorophyll. Leaf size is dependent on adequate zinc and phosphate levels while leaves are forming — meaning early peak nutrient demand. These must be applied at hull split and or post-harvest the season prior.
Chlorophyll production takes place as the leaves expand and requires magnesium, manganese, iron, and sulfur. If these nutrients are deficient as chlorophyll forms leaves will not be as effective in capturing light for photosynthesis especially in the lower canopy which leads to fewer and smaller nuts, weak lower limbs and terminals that are more vulnerable to the complex of diseases leading to lower limb die back.
Lower limb die back is becoming more and more of a severe problem and is causing significant yield reduction and shorter orchard stand life.

Soil nutrient dynamics, growth and yield of green maize and vegetable cowpea with organic-based fertilization Article in Archives of Agronomy and Soil Science 60(2) · February with 20 Reads.
Soil is a major source of nutrients for plant growth. Nutrients supplied by the soil are called mineral nutrients. The non-mineral nutrients such as carbon (C), hydrogen (H) and oxygen (O) come from air and water during photosynthesis.
The growth and yield performance of green maize (Zea mays), followed by a late-season vegetable cowpea (Vigna unguiculata), was assessed with two rates of three different types of organic-based fertilizers (OBFs) fortified with an inorganic nutrient source.

Similar. This paper concerns the agronomic and environmental results from the experiment in terms of crop shoot and root growth, yield, pest and disease damage to vegetable products, nutrient uptake and nitrogen dynamics measured to m soil depth. Results concerning the . The response of crop growth and yield to the nutrient supply can be expressed in growth or yield curves and described by “yield laws”. In practical cropping, nutritive minimum factors are often responsible for unsatisfactory yields and thus present growth problems.
There was also an inorganic fertilizer treatment of NPK 20–10–10 applied at kg ha−1 and a no-fertilizer control treatment. Nutrient movement in the soil Nutrients get to the corn plant in two ways – either the roots grow to the nutrient or the nutrient gets to the roots via soil water.
Changes in soil density can also restrict root growth and nutrient movement. Guide to on-farm trials: Testing your yield potential. About. Nitrogen doesn’t have to be.
