Watch how one customer saw impressive yields after partnering with Holloway

Tom Sandrini, an alfalfa farmer in the Kern Delta area, discusses his experiences with healthier crops and higher yields after partnering with Holloway Ag.

After seven years of using liquid fertilizer, he switched to Holloway Ag’s solid soil amendments and has seen incredible yield over years past. He says that he has never seen his fields so green and lush with growth and that it has kept the weeds completely at bay. The alfalfa develops a regrowth and a canopy so quickly after each cutting that the weeds don’t get any light to grow!

He was also very pleased with Holloway’s effective and efficient spreading process of the soil amendments and compost.

Because of the results, Sandrini says he will get his fields soil tested every year and follow whatever recommendations Holloway sees fit.


Holloway carries a variety of soil amendments and nutrients so that you get the right solution for your field. Many of our soil amendments are certified organic and we take pride in mining and sourcing our products directly. Whether your soil is in need of improved water retention, amelioration of sodium levels, increased organic matter, additional nutrients, or an adjustment to its pH level, the Holloway Ag team has the product to replenish and rejuvenate your soil.

Holloway has 16 different types of soil amendments and nutrients. From various percentages of gypsum and standard blends of gypsum and sulfur, to lime and humic acid, we have a combination soil amendment to treat your particular brand of soil. We also offer micronutrients and both dairy and green waste compost to replenish soil nutrients. Holloway agronomists are also at the ready to analyze your soil report and recommend a custom blend based on the many factors that make up your soil, such as pH levels, natural elements, nutritional density, water retention, and soil type.

Watch how one stone fruit grower improved his soil quality after partnering with Holloway

The agronomy team at Holloway Ag took soil samples at each of Ryan Metzler’s stone fruit orchards to determine deficiencies in the soil and create a custom blend soil amendment prescription to improve the soil, and therefore the tree health.

“I’d highly recommend Holloway and their agronomy team and their sales team if you’re trying to get your soils in a better place.” Metzler said.

Better tree health equals more fruit and better fruit. The Holloway Ag team took an individualized approach to the soil in each orchard to yield the best results for the grower.
