PRODUCTION UNIT / PRODUKSIE EENHEID NB FACTORS IN PLANNING / NB FAKTORE IN BEPLANNING 1. CROP & TARGET MARKET / GEWAS & TEIKEN MARK 2. COST FOR CONSTRUCTION / KOSTE VIR KONSTRUKSIE 3. CLIMATIC CONDITIONS – TYPE & LEVEL OF CLIMATE CONTROL/ KLIMAATSTOESTANDE – TIPE EN VLAK VAN KLIMAATSBEHEER  PLANNING / BEPLANNING GET ADVICE FROM ENGINEER WITH EXPERIENCE IN GREENHOUSE STRUCTURES / KRY ADVIES VAN INGENIEUR MET KWEEKHUIS ONDERVINDING  LOCALITY / LOKALITEIT Factors / Faktore: 1. Market / Mark Type of product (crop) / Tipe produk (gewas) Consumer preferences / Verbruikers voorkeure  LOCALITY / LOKALITEIT 2. Topography / Topografie Open hydroponic system – as level as possible / Oop hidroponiese stelsel so gelyk as moontlik  LOCALITY / LOKALITEIT Closed system – slight slope / Geslote stelsel ‘n effense helling  LOCALITY / LOKALITEIT 2. Topography cont. / Topografie vervolg. Area must be well drained – reduce disease pressure especially important where shadenet is used / Area moet goed gedreineer wees – verminder siektedruk veral belangrik waar skadunet gebruik word.  LOCALITY / LOKALITEIT Trees no closer than 2.5 times their height – shading effect / Bome nie nader as 2.5 keer hul hoogte – skadu effek. Eg. / Bv. Ave height 8 m distance should be 20 m from building. 8×2.5 Gemiddelde hoogte 8 m afstand moet 20m vanaf gebou wees. 8×2.5  LOCALITY / LOKALITEIT High trees or structures to the north, east or west of planned greenhouse structure should be avoided – shade effect / Hoë bome of strukture noord, oos of wes van beplande kweekhuis struktuur moet vermy word – skadu effek.  LOCALITY / LOKALITEIT It is important to consider frost and prevailing wind / Dit is belangrik om ryp en heersende windrigting in ag te neem Adaptations / Aanpassings: 1. In areas where there is frost the site should be higher than the lowest valley. / In areas waar ryp voorkom moet die tonnel opgerig word bo die laagste vallei. 2. In windy areas it should not be on a hill top. In winderige ares moet tonnels nie op die heuwel gevestig word nie.  LOCALITY / LOKALITEIT 3.Water NB: before thinking of doing hydroponics the available water source should be tested for quality and quantity. NB: voor daar begin word met hidroponiese verbouing moet daar gekyk word na die beskikbare waterbronne dit moet getoets word vir kwaliteit en kwantiteit ⭣ or ⭡ pH could lead to unavailability of nutrients. / ⭣ of ⭡ pH can lei tot onbeskikbare voedingstowwe. Alternative to reduce ions in water – reverse osmosis.NB removing ions from water by reverse osmosis filters is very expensive & not advisable. Alternatief om ione in water te verminder – tru-osmose. NB die verwydering van ione van water deur tru-osmose filters is baie duur & word nie aanbeveel nie  LOCALITY / LOKALITEIT 4. Climate / Klimaat eg – tomatoes /bv tamaties In frost-free, subtropical area – little need for climate control. In rypvrye, subtropiese areas – min behoefte vir klimaatsbeheer. Gauteng – cold winter nights – climate control important Gauteng– koue winter nagte – klimaatbeheer belangrik eg lettuce / bv. slaai In tropical areas cooling will be needed during the summer months. Trope sal verkoeling benodig tydens die somer maande In Gauteng ‘n less expensive structure can be used. Gauteng kan ‘n goedkoper struktuur gebruik.  LOCALITY / LOKALITEIT 4. Climate / Klimaat wind probleem - net struktuur wind problem – net structure Waar verskeie faktore geidentifiseer is as beperkende faktore soos bv. temp, humiditeit, wind, lig en CO2 Where various factors identified as limiting factors for example temp. humidity, wind and light and CO2 In SA varieer behoeftes van Oos na Wes & Noord tot Suid In SA needs vary form East to west & North to South Not necessary for a ‘tunnel’ with all the accessories to produce a record yield. Nie nodig vir ‘n tonnel om al die toebehore te he om ‘n rekord opbrengs te lewer nie.  LOCALITY / LOKALITEIT 5. Energiebron/ Energy Source Moet ‘n konstante energiebron wees / Should be a constant energy source Bron bepaal die koste /Source determine cost Algemene bron elektrisiteit- ander bron steenkool (besoedeling) / General source electricity- other source coal (pollution)  LOCALITY / LOKALITEIT 6. Grond / Soil Produksie kan in grond plaasvind./ Production can occur in soil. Grond moet goed deurlug en gedreineer wees. / Soil must be aerated and well drained. Sand – sandleem grond ideaal. / Sandy – sandy loam soils is ideal.  LOCALITY / LOKALITEIT 7. Other farming activities / Ander boerdery aktiwiteite. Must be aware of the surrounding activities that could possibly be a problem in order for farmer to be proactive. Moet bewus wees van die omliggende aktiwiteite wat moontlik ‘n probleem kan wees vir die boer om pro-aktief te wees.  LOCALITY / LOKALITEIT 8. Infrastructure & accessability Infrastruktuur & toeganklikheid Accessibility have influence on transport cost – crop transport to market and receiving of goods. /Toeganklikheid het ‘n invloed op vervoerkoste – gewas Vervoer na mark en ontvangs vir goedere. Distance from harbours and airports should be considered in planning for future exports. / In beplanning moet daar gekyk word na waar hawens & lughawens geleë is vir toekomstige uitvoere. The production unit must be easily accessible for fertilizer & chemical consultants. / Die produksie eenheid moet maklik toeganklik wees vir bemestings en chemiese konsultante.  LOCALITY / LOKALITEIT 9. Room for expansion / Plek vir uitbreiding Area wat aangekoop word moet groter wees as die wat onmiddellik benodig word. / Area acquire should be larger than the immediate needs. Addisionele aspekte wat geakkomodeer word sluit in diensgeboue, store en toegangspaaie. / Additional are to accommodate service buildings, storage and access drives. Area vir ophoping van groeimedium voorraad. / Area for the buildup of growth media stock. ‘n Moontlike dam / poel vir afvoer water om die voedingsinhoud van die water te verminder voor dit in strome en die grondwater tafel bereik. / A possible dam for the runoff water to reduce nutrient content before it reaches streams and the soil water table. PRODUCTION UNIT/ PRODUKSIE EENHEID NB facilities NB Fasiliteite Working space for sorting & packaging Werkspasie vir sortering & verpakking Storage area for fertilizer and growth Stoor area vir bemestingstowwe & medium groeimedia A lockable chemical storage area ‘n Sluitbare chemiese stoor area.
