oh boy, you caught me in a semantic error. i suppose my entire argument is invalid now.
BT is the same things many organic folks seem to have zero problems spraying. are you saying that BT is unsafe? because theres mountains of evidence suggesting otherwise.
i feed loved ones stuff i grow with multiple pesticides applied. i do not allow pseudoscience hysteria to guide my judgment
people have been breeding plants for as long as agriculture has existed. this in of itself is genetic engineering. thousands of genes are swapped when two plants are breed.
are you suggesting that covering farmland with a bug screen is a viable alternative to pesticides/gmo? this is insane.
everything suggested by the organic Luddites will detrementally effect the productivity of farmlands. food is a global commodity, if americans or Chileans or w/e can produce cheap soy or corn or wheat, the effect is profoundly helpful towards poverty stricken individuals.
http://www.supremegr...-benefits-.htmlcan you point me to any study that supports your claim? organic farming methods are terribly inefficient compared to modern agriculture.
i dont understand... are you advocating a return to like... medieval sustenance farming as a realistic solution to feeding the entire planet? idk about you but i dont have the time to chase some asshole chickens around the yard.
there are actually a number of pesticides that are literally safe for consumption. neem and bt are a good example of these. they are literally all but wholly non toxic to humans. coffee is less toxic.
OK, not just a semantic error, but rather maybe a lumping of a company's terrible choices in with some not bad ones....oh boy, you caught me in a semantic error. i suppose my entire argument is invalid now.
so you are saying with beneficial fungi/kelp/aquarium water... we can feed 6 or w/e billion people?
i dont know the numbers but im guessing the world consumes 10s of millions of tons of nitrogen fertilizer. you are saying this kelp and aquarium water or w.e is goint to supplement this entirely? at the same or lower cost? on the same amount of farm land?
hate to be a nit picky asshole, but you linked me basically pr marketing flyers and youtube videos of novel organic methods that granted are interesting... but at the same time wholly unsuited for large scale agriculture.
can you point me to any study that supports your claim? organic farming methods are terribly inefficient compared to modern agriculture.

To an extent, yes. You can only go so big from a farm standpoint before you have to start using harmful farming practices to work the land. The three main problems we run into are pesticides, fertilizers, and soil erosion (though this is in part a direct result from the other two). The best anti-soil erosion techniques include:One of the leading reasons Africa can't grow enough food to sustain its population is because of soil erosion. The modern crops and modern farming practices have worked hard to destroy the land. Their soil is either depleted or blown away by the wind.
- No till farming
- Keyline design (fascinating subject)
- Growing wind breaks to hold the soil
- Getting organic plant matter back into fields
- Stop using chemical fertilizers (which contain salt)
- Protecting soil from water runoff
Chemical fertilizers are not good for the soil or the ground water, no way around it.
Pesticides (herbicides and insecticides) are hit or miss. Some are naturally occurring in some form (BT) but most of them are chemicals and rarely just hit their target. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including nontarget species, air, water, bottom sediments, and food. * Pesticides are also directly responsible for the major loss of pollinators (colony collapse disorder for one). The USDA estimates $200 million in loss in the United States alone from the loss of pollination and pollinators. It is also estimated that pesticides have been responsible for a loss of 1/5th of the honeybee colonies in the US. That isn't just about honey, that has a huge impact on agriculture in general.
This is one of the areas I am passionate about. I don't have any concrete proof but I believe that the increase in diseases and cancers in this nation are a direct result of the chemicals we ingest and are exposed to. If it causes cancer in animals maybe we shouldn't be so quick to spray it on something we would eat.

In the 25-year period between 1950 and 1975, agricultural productivity changed more rapidly than at any other time in American history (fig. 1. See fact sheet). Although the acreage in farming dropped by 6 percent and the hours of farm labor decreased by 60 percent, farm production per hour of on-farm labor practically tripled, and total farm output increased by more than half. These dramatic changes were produced by technological innovations, development of hybrid strains and other genetic improvements, and a fourfold increase in the use of pesticides and fertilizers (fig. 2. See fact sheet).
The result of all these changes has been that agriculture has become more intensive, producing higher yields per acre by relying on greater chemicals use and technological inputs. It also has become more expensive, relying on purchase of machinery and chemicals to replace the heavy labor rcquirements of the past. To remain competitive, farmers have been forced to become more efficient, farming ever larger acreages with bigger equipment and more fertilizers and pesticides. Small farms growing a wide variety of crops have in large part been replaced by much larger farms consisting of extensive fields of a single crop. As a result, the number of farms has dropped by half since 1950, and average farm size has doubled (fig. 3. See fact sheet). Today only 2 percent of U.S. farms produce 70 percent of the vegetables, 50 percent of the fruit and nuts, and 35 percent of the poultry products grown in this country.
Although the intensification of agriculture has vastly increased productivity, it also has had a number of potentially detrimental environmental consequences, ranging from rapid erosion of fertile topsoils to contamination of drinking water supplies by the chemicals used to enhance farmland productivity.
greenhouses dude, they are way cost prohibitive. where they DO make sense is in areas that are way cold to much of the year. canada has an amazing amazing amazing greenhouse industry. they make amazing marketable somewhat cheap tomatoes during the coldest months of the year. those greenhouses however cost millions of dollars per acre. they are not a solution for crops like soy and corn, food staples to say the least.
i agree better irrigation is always a good investment i use netafim drippers and sprayers and i would not give them up for anything. large scale farms use somewhat inefficient methods like those giant circular creeping sprinkler systems howver these are not fertigation systems, they are simply pumping well water. fertilizers are applied to the soil directly.
i personally am a fan of fertigation chemigation techniques. i enjoy perusing this because its an excellent exercise in practical engineering! the rewards i reap are basically 0 labor and excellent control of fertilizers. i am able to run tap water or fertilized water when ever i want. my system can even detect rainfall and delay the system automatically. i dont take advantage of that however, i handle that manually. i dont have much faith in the sensors i have for detecting rain.
at some point i want to get a tipping bucket rain sensor for real quantitative rainfall measurements.
i suspect fertigation could be extented to larger scale commercial operations growing vegetables and other row crops... however its probably not suitable for the large scale grows of stuff like soy and corn that is basically grown 10's of thousands of acres at a time.
