38. Poulson's American Daily Advertiser (Philadelphia newspaper, with interesting articles) April 21, 1836 -- INVENTION BY A NEGRO - A patent given to 29 year-old Henry Blair of Maryland, a free colored man, for a Corn Planter machine now on exhibit at the Capitol - description of process - Blair thinks it will save the labor of eight men - he is adapting the machine for use with cotton. [NOTE: Henry Blair was the only inventor to be identified in the Patent Office records as "a colored man." Blair was born in Montgomery County, Maryland around 1807. He received a patent on October 14, 1834 for a seed planter and a patent in 1836 for a cotton planter. Henry Blair was the second black inventor to receive a patent the first was Thomas Jennings who received a patent in 1821 for a dry cleaning process. Henry Blair signed his patents with an "x" because he could not write. Henry Blair died in 1860.].\n\nImage is available at:\n\nhttp://images.google.com/images?q=tbn:f0WcIWy2gEYMlM:www.library.georgetown.edu\n\nhttp://inventors.about.com/od/blackinventors/ig/African-American-Inventors-/Henry-Blair----X8447.htm\n\nhttp://www.twinlakes.k12.in.us/info/library/connection/inventor.html\n\nmng.1432@gmail.com

gram can be grown in cotton because cotton has a lot of pores which can store water and air. these grams absorb this water and the nutrients along with it and germinate into little seedlings. then they have to be transplaned into the open land so that they can get sufficient nutrients. the small grams need very little water and nutrients to germinate in their initial stages.

MAGNETISM IN AGRICULTURE\n\nThe influence of the geomagnetic field on the growth of plants was scientifically established for the first time in 1862 by the French chemist Louis Pasteur (1822-1985), during his experiments on fermentation, when he discovered that the EarthÍs magnetic field had a stimulating effect on that process.\n\nThe late Dr. Albert Roy Davies, the father of modern bio-magnetics (and the mentor of our Peter Kulish, the American inventor of the presented MAGNETIZER), received a patent in 1950 for magnetically treating seeds to stimulate plant growth. Use of magnets in agriculture is not new and the leading role in this respect goes to the country of Israel. Scientists from the Mineral Engineering Dept. of the renown and prestigious Israel Institute of Technology "TECHNION" in Haifa confirm that the principle of magneto-hydro-dynamics (MHD) permits to lower the surface tension of water, causing the increased solubility and penetration, which stimulates the roots growth.\n\nThe MAGNETIZER has opened a new chapter in the efficient use of magnetism in agriculture.\n\nThe explanation of the principles of its working follows below.\n\nThe lowered surface tension by the monopolar MAGNETIZER system facilitates water absorption into soil and increases solubility. This effect can be seen in case of limited cilia growth. Water treated with the MAGNETIZER de-clogs and breaks up the compressed soil giving the root cilia freedom to absorb water and minerals more quickly and by a larger surface area - in consequence obtaining major growth of roots and plants. Also now the minerals pass easier through water into the roots. Third, and equally important are the electromotive forces that are transferred from water to the plant. These forces, as shown in thousands of experiments and real life applications, specially stimulate the\n\n \ngrowth activity. The root system excited by the electromotive forces of the MAGNETIZER promotes healthier, bigger and quicker plant growth. In drip irrigation, the mineral/scale barrier known as the bowl effect, is dissolved thereby enabling and encouraging the root cilia to grow and expand further into the soil.

Because of the results he got from crossing his pea plants.. It's not like the guy had lots of technology to work with. Power of deduction is what he had.

They couldn't. It took many years of improvements in agricultural technology before that could happen. \n\nThe most useful thing to the serfs was the invention of metal plows. Before that they used a wooden scratch plow. This was designed for tilling soil in the Mediterranean region but was horrible for tilling the hard soil further north. When they were able to make deeper furrows they were able to plant their crops deeper which protected them from the elements resulting in a greater crop yield. \n\nAnother important invention was the creation of a new kind of harness that allowed them to work the land with horses instead of oxen. The old design cut off too much of the horse's windpipe. Naturally, a suffocating horse isn't a good worker. So they used oxen which didn't suffocate but were slow and difficult to work with. With the new harness they could use faster horses and work more of the land.

I think it is awesome what you are doing keep up the good work, everytime someone reads this it is a seed planted, and this is a really good way to plant some seed, God Bless you for the work that you are doing!!

Not very long. The north was far more industrialized the the agrarian south. What the person above said is true as well.

yes james naismith invented basketball. he invented during a summer at YMCA a long ago. he used two peach baskets and a soccer ball.

The first Argonauts of 1848 used quite primitive mining tools: knives, spoons, a shovel, and a pan for washing the gold. Since these miners could only dig out bigger nuggets with such primitive equipment, they had to work on rich gold deposits. In the same year, technical improvements such as the cradle, the rocker, the long tom, and river damming, basically all known since the Middle Ages, were introduced by the more experienced Mexicans. The cradle and the rocker both worked on the same principle: wooden boxes with the top and front piece missing and a sieve on the bottom side through which the dirt containing gold was washed. On the bottom horizontal wooden bars slowed the incoming water down and helped to separate dirt from gold. With a handle on the side of the box, the whole mechanism could be rocked. The rocker required 3 or 4 people to work, one to shovel the dirt into the machine, one responsible for the water supply, and a third one to move the handle. Contrary to the individual washing with the pan, this more efficient technique required miners to find partners, thus establishing small mining groups of 3 to 9 people.\n\nThe long tom functioned similarly to the rocker but increased its efficiency. It also had the shape of a trough, but it was much larger, 12 to 15 feet long and about 2 feet wide. Mainly made out of wood, it had a metal bottom with a sieve and a ripple box at its end. This machine was put up with a slight slope, thus facilitating the water flow. While one man shoveled dirt into the long tom, making sure that the water was running, another mixed water and dirt while taking out big stones that could damage the sieve. At the end of the day, the dirt was taken out of the box and washed in a pan. Six to eight men had to work a long tom to fully exploit its capacities. A few miners started to employ the long tom at the end of 1848, and by 1850 it became a common machine.

I'm not sure if you will be able to find any patent information going back to 1748.  You might try your local county library and see what resources they have.

Damn good question... I know the guy who came up with the patent was named Patent

I could not find the exact number of experiments, but wikipedia says that he tested 28,000 pea plants

Plants which reproduce without seeds appeared first in the history of the Earth.  Plants with seeds appeared much later.
