Onawa, Iowa — Farmer
“I have applied your gypsum product to my fields over the past seven years. I used to have to deep rip these fields to improve the aeration and reduce compaction. Now the soils are soft and I am no longer planning to rip them. This is going to be a cost savings in addition to all the other benefits.”
Woodbine, Iowa Farmer
"I use compost because it provides so many micronutrients , trace elements and microbes that you can't possibly find in commercial fertilizer. It improves organic matter and stimulates soil biology that leads to healthier soil and most importantly higher yields. I have worked with Abe since he started Natural Fertilizer in 2007."
Woodbine, Iowa Farmer and Client since 2009
"Natural Fertilizer Products has been great to work with over the years. Their team knows their stuff and they're always honest and easy to deal with. Their products really work and I like that they are sustainable and made here locally. It is good to work with folks you can trust and who deliver results year after year."
Mt. Vernon, Missouri — Farmer
“I applied 1000 pounds per acre to my grass pastures this year. I can honestly say that this was all I have done different. I graze my dairy cows on this grass. My dairy cow performance has vastly improved. My spring production was about 15#/day higher than in the past and production stayed higher longer into the summer. This summer I am still getting about 20#/day more than I have ever in the past. I have to truck this PRO CAL 40 a long ways, but I will definitely be using more this year.”
Onawa, Iowa — Farmer
"I used PRO CAL 40 on my river bottom ground this last fall. This is a Luton soil (heavy gumbo). This spring we had some 3 inch rains and where I applied PRO CAL 40 the water was gone in hours. The other ground had water standing on it for days."
Rogers, Nebraska — Farmer
"That PRO CAL 40 really wakes up my alfalfa. I was thinking about destroying my alfalfa before I applied PRO CAL 40. I don’t know how the stand improved so much. The yield was greatly improved as well."
Highland, Kansas — Farmer
"In the past my hillsides always turned yellow in August. This year after using PRO CAL 40 (1 ton/acre) on these hillsides only my neighbors hillsides are yellow. My fields are staying green."
Guthrie Center, Iowa — Farmer
"You have a great product in PRO CAL 40. I didn’t see much the first year I think because it was too dry, but after this year I am now a believer."
