Certified Agronomists

Our general approach to agronomy is to partner with the grower, and/or their agronomist and PCA to use facts and science to derive the most cost-effective solutions to improve your yields.

Holloway’s agronomists, either directly for the grower or working with their agronomist and/ or PCA, take a strategic approach to collecting soil, water, and tissue samples. Every field presents a unique challenge, and we collect samples based on both grower and agronomist knowledge. In any given field or block we might collect four or five samples, which we then send to accredited labs for analysis. From there, we make amendment recommendations based on the lab reports. Our agronomists are empowered to make materials recommendations based on the needs of the grower — even if Holloway does not sell the necessary materials.

Holloway Ag’s agronomists took soil samples from Tom Sandrini’s alfalfa farm because there were areas that were high producing and some that struggled. By analyzing the soil, they recommend and applied a gypsum-sulfur blend of soil amendments, as well as a compost blend to help improve yield.

In Sandrini’s first cutting, he produced 2,400 bales and his second cutting 18 days later was 1,000 more bales. All that without watering and only relying on the two irrigations that went in between the fields.

Thirty days later Sandrini did his third cut on his biggest field and it had more hay on the 30 day cycle than it did on the 48 day cycle. One of his smaller fields produced more than 460 bales two times in a row, when the previous year, without Holloway’s amendments, it had only done 400 bales total for the growing season.

On 12 acres he has gotten about 2.5 – 3 tons an acre in seven months using the prescription from Holloway Ag’s agronomy team.

Soil Analysis

Soil Analysis

Holloway’s agronomists have decades of field-assessment experience. It is a best practice to interview the grower and the “guys in the field,” including the irrigator so we can learn about the field’s history.

We also make a point to collect as many samples as necessary so we can get a comprehensive measurement. We generally collect four to six samples in a 40 acre plot. We assess the soil from several points of view: A physical exam tells us if the soil has more sand or clay. Analyzing for the presence of minerals and nutrients, including the soil’s salt load, will tell us if the soil is conducive to growing the crop you want.

Our goal is to prevent growers from wasting money by planting in ground that simply cannot sustain certain crops.

Water Analysis

Water is the most overlooked element when it comes to soil analysis. It’s the “wild card” that many growers forget about. Holloway’s agronomists routinely analyze water in order to assess whether certain minerals and other unwelcome materials are coming from the water.

For example, if you are amending soil with gypsum to offset the soil’s sodium load, but you don’t know the water has high bicarbonate levels, the bicarbonate and gypsum will react to form lime. In that scenario, you’ve made a big investment to add complications to your soil.

Together, soil and water samples tells us what the field needs, and what the rules for amendment are.

Tissue Analysis

Tissue Analysis

Our agronomists routinely select leaves and petioles to analyze for nutrient levels. We think of this tissue analysis as the report card that tells us how the crop is doing in real time. Tissue analysis will tell us what we can do fertility-wise to improve growing conditions to see the crop through its growing cycle.

Holloway will always make the best recommendations for soil amendments and nutrients based on scientific analysis that will affect your bottom line, not on our bottom line. We are confident that this sets us apart.
