Solar powered fertilizer
By: Nearings fault Date: January 19, 2022, 3:58 pm
---------------------------------------------------------
This article is sort of a continuation of a video I posted a
while back. Here is a real world full sized test of a grower
creating their nitrogen as they go to fertilize crops. I see
great potential here especially if they ever figure out the non
plasma generation part to save 90 percent of the energy used ..

I read a couplle of articles on this topic. "Making Fertilizer
out of Thin Air".
The question I have is exactly HOW MUCH fertilizer you can make
with a typical home solar array. How much Juice do you need to
make how much?

OK. you will also need a source of limestone or Pottaium
Hydroxide to neutralize the Nitric Acid. The 2-4 KW Solar array
is supposed to produce ~ 200 lbs equivalent of fertilizer/yr.
Which means you don't have that electricity available for
running lights if it is busy making fertilizer. How many KW
does your solar array output? Do you have a source of limestone
or KOH? If so, you might run a test yourself.
Abstract: Tomatoes at the Center of Irrigation and Technology in
Fresno, California, were grown with
fertilizer produced on-site using electricity from a 2.4-kW
solar array. Nitrogen from the air and irrigation
water were used to produce nitric acid, which was neutralized
using either limestone or potassium
hydroxide to form aqueous solutions of calcium or nitrate.
Tomatoes of the AB 314 variety were planted in
40-ft-long, 4-ft-wide beds and divided into two equal groups –
test and control - with 12 beds per group.
The control group was fertigated using 200 lbs N/acre of UAN-32
and followed UC Davis reference tables
to determine application rate. The test group was integrated
with the on-site fertilizer generator and
fertigated each time water was applied to the field. The
solar-fertilizer system is on-track to produce 200-
lbs N/acre in the course of a year. However, based on the start
date, the fertilizer production system
produced and injected 70 lbs N/acre this first season. Soil,
fertilizer, petiole, and Brix samples were
collected over the course of the season for both groups. Crop
yields from the test and control plot were
33±14 tons/acre and 35±9 tons/acre, respectively. Despite
applying 35% of the nitrogen fertilizer to the test
plot with respect to the control, yields and fruit quality
between the plots were comparable. The ability to
fertigate frequently is intrinsic to on-site fertilizer
generation, and these results suggest that such application
may decrease the required amount through the increased
use-efficiency of fertilizer for a given crop.

The World’s Biggest Vertical Farm Yet Will Fertilize Crops With
Fish Poop
By: RE Date: January 20, 2022, 5:01 am

What are they using to feed the fish? ???
6 Acres equivalent! How many New Yawkers will that feed? And
this is the world's biggest! How much does it cost to run all
the lights and pumps in this building?

[/quote]not economically viable yet but getting close. At north
of 1000 per tonne so 100 per year for an array worth less than
1000... Using their prototype. An interesting technology to
watch. Decentralized, local, a great use of extra array capacity
in the summer months. Not for me I have enough irons in various
fires...

Not even close. That array just makes the fertilizer. You'll
also need a bigger array to power alll the lights and pumps.
Then a still bigger array to heat the building in wintter and
cool it in summer. Then there is the cost of the building
itself...

[/quote]I can buy a watt of solar right now for $0.25 a watt.
You use a dedicated array in the summer to produce fertilizer
and in the winter to supplement your house array due to lower
production. I calculated based on my usage to heat this place
that total household use for everything with heating and cooling
will be under 10000 kwhr per year. The planned array size is
12000 watts. Local solar production is about 1200 Kwhr per
installed kw so 14000 Kwhr and change... My math works.
