A lot of people answered “true” to this and they’re right. But most of the time, we treat it like the opposite is true. We focus on ppms and getting base sats perfect, but we forget that biology is what drives chemistry in the first place. Microbes are free up nutrition. They.

In the soil, biology drives chemistry.

Agronomists, where is the main place you go to learn more agronomy? If other, add it in the comments.

RuBisCo. What is it?. Ribulose-1,5-biphosphate carboxylase-oxygen-ase (RuBisCo) is a hugely important enzyme involved in photosynthesis. It is actually involved in the first step of fixing atmospheric carbon dioxide. Is it good at its job?. Not really. Research has shown that

When it gets hot what happens?. C3 plants: first organic acid made in the process has 3 carbons. During photosynthesis there are light and dark reactions. One takes place in the light and one doesn’t need light. In the case of C3 plants, both light and dark reactions take place

Sugar (and I don’t mean molasses) is the currency for the whole biological system in the soil. The quality and quantity of the biological system is determined by how much sugar is produced (and shared) via photosynthesis. If we want more biological activity, we must find ways.

Which contributes more to soil OM?. •Above ground growth (leaves & stalks/stems).•Below ground (root exudates & roots).

Agronomists, if you had to guess, how much per year do you spend on education for yourself to better your work?.

This small portion of the Carbon Cycle just fascinates me. It’s so simple, yet so complex. The thought that a plant takes in CO₂ through its conveniently placed stomates (under side of the leaf), fixes that CO₂, shares that fixed CO₂ (sugar) with soil microbes via root

Biofilm or Bacterial Slime. How does something as small as a microbe not get lost in the soil? You’d think with any excess water, all biology would be washed away. To combat this, microbes produce a slime to help them stay put. That same slime:. •Protects biology from drying

All Nitrogen applications are biological in nature. What I mean is that with adequate N applications, biology thrives. Too much, and carbon is burnt up. Too little, the crop suffers (in part because of biology) and carbon is burnt up. Microbes need roughly 8 parts carbon to 1.

Here’s a lengthy post, but a worthwhile read on soil testing. TESTING FOR NUTRIENT NEEDS. “if a soil test says that a soil has 20 parts per million (ppm) of phosphorus (equivalent to 40 pounds per acre), and a crop requires 50 pounds per acre, it would seem that you simply need.

Did you know?. Bacillus Subtilus . This microbe eats other microbes in the soil (Well, kind of. More like suppresses and kills). One that would be of interest is a pathogen like Fusarium, which we know causes root and stalk rots. Fun fact:. During WWII, German soldiers.

A recent paper on the importance of earthworms states, “earthworms contribute to roughly 6.5% of global grain (maize, rice, wheat, barley) production and 2.3% of legume production, equivalent to over 140 million metric tons annually.” . The paper also states that, “less

This is my favorite book that I’ve read in 2025. Will it change my daily work in agronomy? In one sense, no. I don’t work with anyone who does vermicomposting and most operations are too big to consider vermicast. In another sense, this book encouraged me to think differently

How much does stress impact a crop?. “If record yields are assumed to represent plant growth under ideal conditions, then the losses associated with biotic and abiotic stress can reduce average productivity by 65-87%, depending on the crop.”. Buchanan, Bob. et al. Biochemistry &

I believe there is a lot of room for nuance and even different approaches when soil fertility is discussed. But, this is just not true. The MAP/DAP discussion is a problem on its own, but just consider the Bray P1 and Bray P2 topic. Do plant roots send out organic acids as.
