why always root go down & stamp go up from sead in the soil?
95501
It is because of a plant hormone and also becasue plants are sensitive to light moisture and gravity.  shoots or stamp grow towards light and against the force if gravity.  roots grow towards moisture and in the direction of gravity.\n\nIn the shoot, hormone collects on the lower side and stimualtes the growth of the cells on this side.  therefore the shoot grows upwards and away from the force of gravity.\n\nin the root, the hormone also collects on the lower side buts slows down the growth of the the cells on this side.  therefore the roots grows downwards and towards the force of gravity.

The last answer is correct.\n\nLimestone acts to raise the pH of the soil. It is basic which means it is on the base end of the pH scale.\n\nThe reason limestone is a base is b/c of its composition. Limestone is calcium carbonate or CaCO3. The calcium is the base.\n\nIf you are interested in learning more about soil pH & other factors affecting soil, check out the link to the US Dept. of Agriculture.

Most need sandy soil that drains very well in order to grow
389541
Their roots are actually specialized branches (rhizoids) that grow in the ground or into tree bark, on rock, etc. so the whole plant is actually living sideways.  The branches absorb water just like roots would. They have a great capacity for storing water, and most are pretty small, so they don't need as much rain as most plants, just humidity/moistness.  Most surfaces are wet with dew in the morning, and they absorb this.

How capillary action makes water go up...???\n\nEven though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action (pronounced kap uh LAR ee, is the tendency of liquids to move into or out of tiny, hairlike passageways) . This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plant's roots upwards to the plant's highest leafs via capillary action. Try this experiment to see capillary action in action.\n\nWrap the plastic wrap around the knitting needle and then tape the edges so that you have formed a tube. Remember, the narrower the tube, the more pronounced the capillary effect will be. \nOnce you have taped the plastic wrap, pull out the knitting needle. Make sure that the new plastic tube is not bent and is open at both ends. \nNow pour a little of the food coloring into a glass half filled with water. \nNow place your plastic tube into the glass of water. \nExamine the tube carefully. The dye should climb up the tube above the level of the liquid in the glass. \nNow try the same experiment with varying levels of water in the glass. Does this make a difference?

an airpocket is better known as  turblulance. it is either a up draft or a down draft. it is better to find airpockets in the summer time.  if you are taking off in an airplane, as soon as the airplane is airborne  you may some times feel the airplane dip   toward the ground if you are over water  at low altitudes  nothing really changes. However if you are over trees radiation from the ground  will cause the plane  to give you the up or down feeling. as wind flows over the earth  it is give interference  with trees houses   anything really.  thunderstorms  create updartfts and downd drafts.  updraft  during the building stages. and downd dratfs  during the disappating stage.  so you would find a great deal oaf "airpockts"

Sandy Soil\nEasy to cultivate and warm up quickly in spring. It drains well so the plants do not stand with their roots in water for too long. However, as it drains quickly, plants need to be regularly watered and fed if they are to thrive.\n\nSilty Soil \nThis soil type is richer in nutrients than sandy soil. It is also heavier because it can retain moisture and has a tendency to become compacted. It does however tend to drain well and much easier to cultivate than clay.\n\nClay Soil\nWeighty to lift and difficult to work. Drainage is usually bad; the soil is acid and clinging to the feet in wet weather. When preparing the beds for vegetables in clay soil, the organic fertilizer should be added at a rate of two bucketfuls to the sq. yd.\n\nLoamy Soil \nContain sand, silt and clay, in such well-balanced proportions that none produces a dominating influence. These are amongst the most fertile soils. Almost any crop can be grown in them. They warm up quickly in spring and rarely dry out in summer.\n\nChalk Soil\nIt fertility depends largely on the depth of soil overlaying the chalk bed formation. If the topsoil is thin the ground will be poor and hungry. It will be bone dry in summer and the plants will need far more watering and feeding than on any other soil. If however, it is fairly deep, good growing conditions are possible.\n\nPeaty Soil \nIt occurs in fen or boggy areas. Peat is composed of excessive quantities of humus and is associated with water-logging. The soil is usually very acid and contains few nutrients. It does have one advantage in that it warms up quickly in spring. It is excellent for plant growth if fertilizer is added.

yes, you are right- the ideas of up and down are indeed relative. On earth, we have a wonderous and magical force called gravity- which solves the problem easily as we are best one way up really. so technically, neither you nor the paper is upside down. It does however make sense to assume in such a situation that the paper is at fault and turn it round, rather than yourself. Or does that pose another question?

The level of the water actually goes up in other places when the water level goes down at your house.  This is what causes the tide to go out.

Yes I do. It is when a potted plants/flowers roots are growing to big for the current planter it is in. You just need to replant it in a larger pot!!

This is more of a biological question, but as water enters soil, a plant's roots will essentially "drink" the water and provide the plant with it. The process of how the plant takes in the water is unknown at least to me.

If I'm not wrong, the two are directly proportional - the more the nutrients in the soil, the more they would favour plant growth by the synthesis of proteins and hence better and greater yield. \nBut I think this would go on till a certain point ( it might be the saturation point or something). I mean, if your bestow the soil wholly with more minerals and nutrients than the plants need, it won't give you more yield, because then the yield rate will be limited by other factors such as light and carbon dioxide. If you then increase the latter two factors, then the yield will increase again.\n\n[Again, I'm not sure about this....someone please correct me if I'm wrong!!]\n\nEDIT: Ah, there you go.....Fred gave a more thorough explanation.

It's hard to say. Soil doesn't actually grow. It is produced from weathering of rocks that get transported and also degradation of biogenic material. Therefore, the growth (increase) of soil depends on how much rock debris and biogenic material is added to the soil in a certain place. The reverse can also happen. Soil erosion can cause soil to be reduced in a certain place. So, there's no straight forward answer to your question. However, if there is no change in the soil, then, due to the higher specific gravity of a coin compared to soil, it will gradually sink in the soil when subject to rain and other sources of water. But, how much it will sink depends on the type of soil and amount of water received by the ground.

#1 Because not all roots are edible.\n#2 Do we NEED to eat all types of roots because there's so many other things to eat.

Beans like to climb. If you give them alot to climb on and keep them off the ground they will grow to astonishing heights. The main thing to do when planting anything you want to propogate and grow well is the "preparation". If you are starting a new garden, then pick your spot and strip a couple inches of grass and roots off of the area. Put a border around the area that is below the grade by at least 2" - 6 " ( the deeper the better to keep out the unwanted grass and weeds) Next till the soil with a roto-tiller preferably or by hand if you wish. Either way you want to pulverize the earth into a fine smooth mixture. depending on what you are working with and what you are planting, you may want to add something to the soil to give it a boost for your plants/seeds. ie. compost, top soil, sand (if too clayish) whatever it takes to make a dark rich soil. (except for tuber plants which like more sandier soils) Anyway once you pulverize and aerate the soil it sould be alot higher than the surrounding grade. next pull the soil in to the middle from the edging creating a ditch around your garden for run off. Now level the rest of the area being careful not to fill in your ditch. Note: step on the area as little as possible so you wont compact the soil again. Now that you have it all leveled out you can make rows about 12 - 18" wide with a walking ditch beside each row. So essentially what youi'll have is from left to right the outer ditch a row with a peak going down into another walking ditch and then a row peak and so on until you reach the other side. Now you are ready to plant. Follow directions on plants/seeds for spacing. Also you should plant taller plants behind shorter growing ones. Behind meaning that the shorter growing plants get sunlight and not shade from tall plants. Also climbers i.e. beans should be at one end or side depending on sun orientation. The ditches will provide ample area for watering your plants. Water your plants themselves before or after they get their sun not during. you can water in the ditches anytime as long as you don't wet the plants themselves. Hope this helps you. I've been gardening for many years and in every type of climate. Good luck and many stressless days ... gardening one of the last stress relievers that you can enjoy all through the winter months .... my freezer is always full of something from the garden.

hit a bit lower on the ball and follow all the way through..as for it going to the right..that could be because your foot is open when you hit it try hitting with your instep..and keep your plant foot aimed at your intened target... i hope that helps!!
