Calcium - Key Regulator

In the article "How Plants Manage Calcium May Reduce Effects of Acid Rain" from National Science Foundation shows the importance of calcium.

"Our findings should help scientists understand how plant ecosystems respond to soil calcium depletion and to design appropriate strategies to protect the environment," said Zhen-Ming Pei, a Duke University biologist who led the study, which is published in the March 9, issue of the journal Science.""

To grow, a plant needs a reliable supply of calcium, which enters the plant dissolved in water the roots take in from surrounding soil. As the water circulates through a plant, dissolved calcium gets shuttled where it is needed to give the plant's cells their structural rigidity. But calcium supplies coming into the plant cycle up and down over the course of the day, dropping to a minimum at night.

"Calcium is a key regulator of vital physiological functions in both plants and animals," said Maryanna Henkart, director of NSF's Division of Molecular and Cellular Biosciences. ""The discovery of the relationship between calcium in soil, in plant cells, and cellular mechanisms sheds new light on the role of this important mineral in plant growth and development.""

Plants use molecular sensors and flows of chemical messengers to detect and regulate the storage and distribution of vital nutrients such as water and calcium. To track the calcium sensors in the laboratory plant Arabidopsis, Pei and his coworkers used molecules originally found in jellyfish that emit light in the presence of calcium. To deduce the calcium sensor's role, the researchers also introduced an altered version of the sensor protein that abolishes the sensor's effects.

According to Pei, the sensors try to detect how much calcium there is and coordinate that level with growth and development. "If the sensors detect there is not enough calcium, they may tell the plant to hold off on growing, at least until it gets more calcium."

Although acid rain robs soil of much of its calcium, enough is still left for plants to live on, Pei added. But he suspects that sensors may misinterpret "less" as "too little" in those plants and unnecessarily signal for growth shutdowns.

"Some soils have lost as much as 75 percent of their calcium during the past century," Pei said. "One way to respond is to add new calcium to the soil. But we can't do that everywhere that it's needed, and it is also expensive. Perhaps a plant's calcium sensors could instead be tricked into interpreting "less" as "still enough" and keep building new cell walls.""

New findings about how plants function

When Under Attack, Plants Can Signal Microbial Friends For Help

The finding quashes the misperception that plants are “sitting ducks”--at the mercy of passing pathogens--and sheds new light on a sophisticated signaling system inside plants that rivals the nervous system in humans and animals.

How Roots Control Plant Shoots: Biologists Discover Gene That Helps Roots Limit Leaf Growth

University of Utah biologists discovered a gene that allows a plant's roots to tell the leaves to stop growing, presumably when water is scarce, soil is too compacted or other conditions are bad.

I found these two article very interesting, but what does that mean to a corn and soybean farmer? To grow higher yielding crops we really must focus more on the soil. These means much more than just N-P and K, it means making sure that the 20 nutirents for growth are available, that you do not have a hard pan, that the soil drains properly, has a good soil density so that benificial bacteria and biology can thrive to help you crops grow better.

We've been helping farmers develop better soil quality for over 10 years, SuperCal 98G and SuperCal SO4 is a good start... once you've taken proper soil samples. Contact one of our dealers or give us a call, now is the perfect time to get started making better soil!

Double income hit

It seems like the economy is in a tailspin, the Dow is down 2800 points in less than 2 weeks, corn and soybeans are down 30% off their highs. Commodities are dropping which is bringing the cost of fuel down dramatically, and fertilizer is dropping too, though not nearly fast enough.

So what are you going to do with your fertility plan? Cut dramatically due to the drop in commodities? Shoot for maximum yield as always? Cut P and K and wait for the drop in fertilizer? Do you even have a plan?

Yes fertilizer is expensive, yes the commodity market is tanking, but are you going to take a double hit of lower yields and lower prices? While it may not be a yield to build your P and K levels, if they are low (under 15ppm Bray P and 100ppm K at 10 CEC) then it will more than pay to add them in.

What about your pH? Think you can afford to forgo the lime. At a pH of 6 you could be missing out on an additional $200 of income at today's prices, even more if you pH is lower.

The cost of SuperCal 98G has remained relatively unchanged over the past 3 years making it this year's best value. The University of Wisconsin has stated that liming where needed can increase yield 10%-40%.

So even if corn is $3 next year, and you can raise you yield from 150 to 165 a 10% increase and about a 2 to 1 return on investment in the same year when 98G is used (very conservative numbers used). Why spend $50-$100 per acre for tons of aglime and then wait 2-7 years for a return. Apply SuperCal 98G for a fraction of the cost and put grain in the bin in the same season.
