Hilling
open-in-new
<h2 id="examples">Examples</h2> <p>A common application of hilling is for potatoes. The tubers grow just below the surface, and can produce <a href="/facts/Chlorophyll/1Sb0NyyM">chlorophyll</a> and <a href="/facts/Solanine/Iwxa3UI5">solanine</a> if exposed to light (green potatoes). Solanine is <a href="/facts/Toxic/qa96rs60">toxic</a> in large doses, and can result in <a href="/facts/Nausea/dyhkcbeD">nausea</a>, <a href="/facts/Headache/mdmmC9DP">headache</a>, and in rare cases, <a href="/facts/Death/VJmq29qm">death</a>. By hilling one or more times during the <a href="/facts/Growing_season/6w2eMvyr">growing season</a> – effectively, burying the potatoes in an additional few inches of soil – <a href="/facts/Crop_yield/hmE59fhk">yield</a> is improved, and the <a href="/facts/Harvest/a4Lywf6p">harvest</a> remains edible. </p><p>In vineyards, at the beginning of the winter period: </p> <ul><li>reduces the risk of damage by frost. Indeed, a heat gradient is formed by the thermal inertia of the earth. It is warmer inside the mound of soil.</li> <li>facilitates the flow of water (which presence is important because of precipitation during winter). The evacuation can be done via grooves.</li> <li>destroys weeds.</li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="https://www.youtube.com/watch?v=F7l_DOlx1Uo">How To Grow Potatoes : How to Hill Potatoes</a> <a href="/facts/YouTube/db276jst">YouTube</a></li> <li><a href="https://archive.today/20130202231151/http://www.springerlink.com/content/t62n0w1vw1641365/">Timing of herbicide application and potato hilling</a> American Journal of Potato Research</li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Clayton, E.
