Forest-Friendly Ways to Get More From Pine

Pine is an important part of the U.S. lumber and paper industries. But it has an economic drawback that its growers know all too well: It can take 30 years or more for a pine stand to mature and turn a profit.

That's why Agricultural Research Service (ARS) scientists Daniel Pote and David Burner are working on environmentally friendly strategies that commercial pine growers can use to get the most from their stands. Pote, a soil scientist, and Burner, an agronomist, conduct their research on 60 acres of pine planted at and near the ARS Dale Bumpers Small Farms Research Center in Booneville, Ark.One aspect that they concentrate on is harvesting fallen pine needles as "straw" for use as landscaping mulch.

A main goal is helping growers supplement their income from their pine stands while still keeping the stands' environment intact and viable.According to Pote, pine straw tends to interlock and stay in place better than most other mulches while still retaining a loose, open structure that allows air, nutrients and water to easily reach the soil surface.

So he's concerned that forests and watersheds from which pine straw is harvested could suffer from the loss of these benefits.Pote's studies showed that although harvesting pine straw increases runoff, soil erosion and some nutrient loss, these impacts can be softened by less-frequent harvesting.

He noted that growing forage under the pine-tree canopy to hold soil in place when straw is removed is a conservation method worth considering.Meanwhile, Burner is studying how spacing and fertilization of trees affects pine straw yield. He's also examining how wider applications of agroforestry practices involving pine can boost income from millions of farm acres that are of marginal quality for crop production.

His focus is on silvopasturing, a practice that combines tree-growing with forage and livestock production.Read more about the research in the July 2006 issue of Agricultural Research magazine, available online at: http://www.ars.usda.gov/is/AR/archive/jul06/forest0706.htm.

TITLE: FOREST-FRIENDLY WAYS TO GET MORE FROM PINE


ALAM BA NINYO NA GUMAGAWA NG PANANALIKSIK NGAYON ANG MGA EKSPERTO SA MAS KAPAKI-PAKINABANG NA PLANTASYON NG PINE TREES MULA SA LUMANG PAMAMARAAN.

ALAM NAMAN NATIN NA MARAMING TAON – MGA 30 TAON ANG DAPAT NA GUGULIN PARA MAPAKINABANGAN NG HUSTO ANG PINE TREES.

NAGHAHANAP NG MGA MAS MAKABAGONG STRATEHIYA ANG MGA SIYENTISTA SA AGRICULTURAL RESEARCH SERVICE SA PANGUNGUNA NINA SOIL SCIENTIST DANIEL POTE AT AGRONOMIST DAVID BURNER PARA MADAGDAGAN NG MGA MAGSASAKA ANG KITA HABANG NAGHIHINTAY NA PAKINABANGAN ANG PINE TREES.

ISA SA NAPAGTUNAN NILA NG PANSIN AY ANG PAKINABANG MULA SA PINE STRAW O PINE NEEDLES NA MAAARING MAGAMIT BILANG LANDSCAPING MULCH.

NAPATUNAYAN NG MGA EKSPERTO NA ANG PINE STRAW AY MAY KAKAYANAN NA MAPANATILI SA IISANG LUGAR AT MAS MAINAM KESA SA IBA PANG MATERYALES SA MULCHING HABANG NAPAPANATILI NITO ANG LOOSE, OPEN STRUCTURE PARA MAKAPASOK ANG HANGIN, SUSTANSIYA, AT TUBIG PATUNGO SA LUPAIN.

SAMANTALA, NAIS NAMANG ISULONG NG MGA EKSPERTO ANG TINATAWAG NA SILVOPASTURING, ISANG PRAKTIS NA KUMBINAYSON NG PAGPAPALAKI NG PUNUNGKAHOY, PAGTATANIM PAGPAPALAKI NG FORAGE AT MGA ALAGANG HAYOP.
